摘要： A spectral and power shaping mapper for high data rate signaling modem functions in a first mode having spectral and power shaping and using convolutional encoding, a second mode having power shaping, a third mode having power shaping using convolutional encoding, and a fourth mode having straight-forward mapping. Based on data rates and other criteria, incoming bits are grouped together, with a first subgroup of bits used in the first mode to generate two sign vectors (and in the other modes a single vector), a second subgroup of bits used in conjunction with an appended bit in the first, second and third modes to generate at least two magnitude manipulation vectors, and a third subgroup of bits used in a modulus converter to generate a plurality of quotients. The quotients and magnitude manipulation vector(s) are used to select one, two or four sequences of constellation points from a multidimensional constellation depending on mode. The sequences of selected points are combined with the sign vector(s) to generate, one, two or four sequences of octets for a shaping selector. In the first and third modes, the shaping selector employs a convolutional encoder state machine which uses criteria such as lowest cost paths and/or lowest average power in order to select which sequence of octets to output. In the second mode, selection is based on power only. In the fourth mode, the generated octets are output as there is no choice of octets.

Based on data rates and other criteria, groups of incoming bits are grouped together, with a first subgroup of bits being used to generate two sign vectors, a second subgroup of bits being used in conjunction with an appended bit to generate two magnitude manipulation vectors, and a third subgroup of bits being used in a modulus converter to generate a plurality of quotients (r.sub.k). The quotients and magnitude manipulation vectors are used to select two or more sequences of constellation points from a multidimensional constellation. The sequences of selected points are combined with the sign vectors to generate four sequences of octets for a shaping selector.

摘要： A method of providing a high bit rate DMT signal includes providing information on a plurality of DMT tones, with at least two of the plurality of DMT tones sending information in parallel. Of the tones sending information in parallel, at least one has a SNR too low to be individually used for the number of bits it is transmitting. Accordingly, the tones are coherently “combined” at the receiver in order to generate a SNR sufficient together to carry, at the desired BER, the number of bits being transmitted in parallel. Two or more tones which alone cannot carry a single bit of information may be used together to provide a sufficient SNR at the receiver to transmit one or more bits. Similarly, two or more tones which alone cannot carry two bits of information, may be used together via parallel transmission to provide a sufficient SNR at the receiver. Further, the bit-carrying capacity of a first tone which can carry one or more bits may be increased by transmitting an increased number of bits in parallel with one or more additional tones which cannot carry any bits of information. According to another embodiment of the invention, rather than sending two or more DMT tones in parallel, one or more DMT tones are repeated over a plurality of DMT symbols, and “combined” coherently in order to generate a SNR sufficient together to carry the number of bits being carried by the repeated tone.

摘要： A PCM modem equalizer includes an RBS estimator and decision modulator in conjunction with an adaptive equalizer such as a conventional decision feedback equalizer (DFE). The RBS estimator and decision modulator receives error signals from the second summer in the equalizer, receives the estimated R signals from the first summer of the equalizer, and outputs a gain correction signal which is applied to the output of the reference generator before the reference generator output is applied to the feedback equalizer and the second summer. The methods of the invention are based on the recognition that the effects of RBS can be detected in the amplitude modulation of the main training sequence stream. The modulation will occur in a periodic repetitive pattern of length 6*T where T is the symbol interval. Therefore, the invention applies a corrective gain to the decision in each time slot in a periodic manner having the same period 6*T. For each time interval T.sub.k over a period of 6*T, the symbol present at the time interval is sampled and a respective corrective gain g(6k-j) is applied to it, where j has the values 0 through 5. The gain applied to each of the six time slots is adaptively updated over a training period until each of the six gain coefficients is optimized.

摘要： A modem includes an LDPC encoder which utilizes a deterministic H-matrix, optionally via a generation matrix, to generate redundant parity bits for a bit block. Ones are placed into the H-matrix in a completely diagonal manner with diagonals subdivided into sets of diagonals. The first diagonal in each set i begins with coordinates H(1,k), where k=(1+(i*Mj)). The remaining diagonals in the sets are offset from the first diagonals so that the column distances between any two pairs of diagonals is unique. In another embodiment, the H-matrix is determined by assigning “1s” in a first column, and then assigning “1s” of subsequent columns deterministically by causing each “1” in a previous ancestor column to generate a “1” in the next descendant column based on the rule that a descendant is placed one position below an ancestor except where rectangles would be generated. Interrupted descending diagonals are generated.

摘要： An easily implementable soft decision decoding (SDD) metric is provided for telecommunications systems and apparatus. The SDD metric is based on weighted average distances or weighted minimum distances between scaled received signals and all reference signals related to the corresponding binary symbol. An important property of the SDD metric of the invention is that the distance weight is completely defined by the received signal scaling factor which is readily available as a result of conventional frequency domain equalization procedures. The invention is particularly advantageous in wireless systems having variable parameters such as wireless OFDM systems with selective fading.

摘要： A pulse amplitude modulated (PAM) mapper includes a constellation matrix memory which stores indications of a plurality of different constellations, wherein at least one of the different stored constellations is of different dimension than another of the stored constellations. The constellations are used individually or together to support a plurality of different modem data rates. In a preferred embodiment, in addition to the constellation matrix memory, the mapper includes a logic block, a constellation controller, a PAM code generation block, and an output register. The logic block receives incoming bits of information, groups the bits as a function of the desired or agreed upon bit rate as indicated by the constellation controller, and provides a plurality of each group of bits to the PAM code generation block, and one or more sign bits to the output register. The PAM code generation block uses the provided bits to choose at least one point from one of the constellations, and uses each chosen constellation point to generate a seven-bit PAM code (typically .mu.-law or A-law code value) word. Each seven-bit output is provided to the output register, and together with associated sign bits generates output bytes. Algorithms are provided for choosing multiple points from the 2D and higher dimensional constellations from provided groups of bits.

摘要： A multiharmonic adaptive phase jitter compensator for a high speed modem is provided. The compensator includes an IIR filter for each harmonic of phase jitter for which compensation is desired. The coefficient update of each IIR filter as well as the input to the primary jitter frequency IIR receives identical information from a phase detector which compares an equalized phase corrected signal entering a decision means with the ideal point determined by the decision means. However, the IIRs for the higher harmonics are trained with different information. Thus, the primary jitter frequency as adaptively determined by the first IIR is fed to harmonic computation circuitry. The harmonic computation circuitry then provides an adapted second harmonic to the second harmonic IIR, and adapted third harmonic to the third harmonic IIR, etc. The outputs of all the IIRs are summed, and the cosine and sine of the sum are provided to phase correct the equalized signal before it enters the decision circuitry.
