摘要： Using the concepts of inverse multiplexing, repeaterless backhaul can be provided on loaded or unloaded loops. Inverse multiplexing can effectively support a large bit rate capacity between the conversion equipment and the CO-side equipment by utilizing a large enough number of potentially low capacity loops. As the distance that the data has to be backhauled increases, the bit rate capacities of the loops generally decrease. However, this decrease in the bit rate capacities of the loops can be compensated for by using inverse multiplexing to gather together enough loops to meet the data rate requirements for backhauling customer data given various service level and contention criteria.

摘要： Indirect digital subscriber line (DSL) service generally involves connecting conversion equipment that converts between DSL service delivered to a customer premises and DSL service that connects back to a data network. Indirect DSL service may be delivered on the same loop to the customer premises that also carries a native 0-4 KHz POTS interface. For larger deployments, the conversion equipment may include inverse multiplexing to combine multiple links back to the data network to support DSL service. Furthermore, the conversion equipment may include functions to digitize the POTS service. Aggregating DSL data from multiple customers and/or digitizing POTS service that may be multiplexed with the DSL data allows for significant pair gain opportunities.

摘要： Fractional bit rate encoding in a pulse amplitude modulation (PAM) communication environment allows the transmission of fractional bit rates, thus maximizing the use of signal-to-noise ratio (SNR) available on a communication channel. The invention allows the transmission of fractional bit rates in a PAM transceiver, thus allowing the encoding and transmission of a fractional number of bits on each PAM transmit symbol. By encoding a non-integer number of bits, a non power-of-two number of PAM levels can be encoded.

摘要： A discrete multi-tone (DMT) digital subscriber line (DSL) communication device employs a linear block interleaver for mathematically combining multiple tones into n-tone combinations in order to efficiently suppress or eliminate correlated noise or impulse noise generated in the communication channel. In architecture, the linear block interleaver includes logic configured to combine multiple signaling constellations into n-tone combinations. The multiple constellations are mathematically combined such that noise energy present in at least one of the n-tone combinations is spread among each of the multiple tones, thus reducing the energy of the noise on each of the multiple tones.

摘要： In a system that uses a dither signal in the production of a transmitted signal, the recoverability of an original trellis code is maintained while forming the dither signal using a modulo value that is equal to the distance between two adjacent symbols. This is accomplished by forming individual modulo counts for each of the orthogonal components produced by the transmitter's 3-tap FIR filter. The modulo counts and the bits from the trellis encoder are used to substitute the constellation subset identified by the trellis encoder with another constellation subset. The substituted subset is used for transmission and results in recovery of the original trellis code by the trellis decoder in the receiver.

摘要： The relative amounts of additive white noise and proportional noise in a communication channel are compensated for by providing adaptive precoding and preemphasis to signal point signals. The amounts of precoding and preemphasis are controlled using scalars to modify the magnitudes of the precoding and preemphasis signals that are combined with the signal point signals. The values of the scalars are transferred between the transmitter and receiver, and the values can be changed without losing synchronization between the transmitter and receiver.

摘要： In order to mitigate against the multiplicative noise effects caused by known non-linearities in a trellis coded data transmission system, a signal constellation is formed by starting with a base constellation whose number of signal points and whose geometry are selected in accordance with conventional criteria and then warping that constellation by adjusting the positions of its signal points in accordance with a warp function which is the inverse of the known component of the non-linear characteristic of the transmission system. Because the constellation warping is deterministic, it is possible for the receiver to "unwarp" the received signal points prior to applying them to the Viterbi decoder.
摘要翻译：为了减轻网格编码数据传输系统中由已知非线性引起的乘法噪声影响，通过从基本星座开始形成信号星座，该基座星座的信号点数量及其几何形状根据常规标准进行选择，然后根据作为传输系统的非线性特性的已知分量的倒数的扭曲函数调整其信号点的位置来扭曲该星座。因为星座翘曲是确定性的，所以接收机在将它们应用于维特比解码器之前可以“接收”接收到的信号点。
