摘要： Methods and systems for communicating in a wireless network may distinguish different types of packet structures by modifying the phase of a modulation constellation, such as a binary phase shift keying (BPSK) constellation, in a signal field. Receiving devices may identify the type of packet structure associated with a transmission or whether the signal field is present by the phase of the modulation constellation used for mapping for the signal field. In one embodiment, the phase of the modulation constellation may be determined by examining the energy of the I and Q components after Fast Fourier Transform. Various specific embodiments and variations are also disclosed.

摘要： A DSL transmitter and receiver are disclosed that efficiently estimate crosstalk interference. When transmitting over a DSL cable, each of the lines of the cable cause interference in the signals traveling though the other lines in the form of crosstalk. In order to reduce the complexity of the crosstalk estimation calculations, the transmitter sends a measurement signal whose matrix includes a plurality of sub-matrices that include less than all of the signal slots and are modulated with QAM +1s or −1s. Meanwhile, the remaining signal slots are modified with QAM 0 s, which do not require any processing during the crosstalk estimation. Rather than calculating crosstalk vectors of all lines, the receiver need only calculate the crosstalk vectors for the signal slots contained within the sub-matrices, thereby significantly reducing complexity.
摘要翻译：公开了一种有效估计串扰干扰的DSL发射机和接收机。当通过DSL电缆发送时，电缆的每条线路以串扰的形式干扰通过其他线路传播的信号。为了降低串扰估计计算的复杂度，发射机发送一个测量信号，该信号的矩阵包括少于所有信号时隙的多个子矩阵，并用QAM + 1s或-1s进行调制。同时，剩余的信号时隙用QAM 0修改，在串扰估计中不需要任何处理。接收机不需要计算所有线路的串扰向量，而只需要计算包含在子矩阵内的信号时隙的串扰向量，从而显着降低复杂度。

摘要： A method for generating a compound signal wave with one or more substantially sinusoidal waveform(s) containing an encoded digital information combined with a variable phase changing waveform(s) producing a compound notched sinusoid waveform that includes at least a sine wave that is amplitude-time modulated and at least one phase modulated wave(s). The encoded digital information can be 1 to n bits per cycle limited only by hardware clock speeds. The phase shifting modulation can be implemented as data or control function(s) with real-time adjustment (within a cycle) of data control, data management, and data security. The compound signal wave is transmitted through existing communication channels or a program controlled modulator with 0 to n degrees (levels) of phase modulation. On the receive end of the communications channel the received signal containing the amplitude-time modulated wave and the phase modulated wave(s) are interrupted by either a decoding of amplitude-time modulation distortions by existing hardware or a program controlled demodulator with 1 to n degrees (levels) of phase modulation. Data values can be directly encoded or contained in a look up table or list. Presence or absence of change to a wave's sinusoidal amplitude within a phase indicates a data value. These data values can be changed within a data cycle or packet. Reduced modulation distortion is exhibited by amplitude-time modulation techniques when compared to classical amplitude modulation techniques. This reduced distortion in a communications signal results in increased effective transmission lengths, reduced error rates, higher data rates, and improved data security (real-time control of values, phase, and control exacerbate snooping attempts).

摘要： In one embodiment, a device (e.g., a transmitter) determines a level of error protection of each bit position within symbols of a particular constellation map used for modulation-based communication, and also determines priority levels of application data bits to be placed into a communication frame. Application data bits may then be placed into symbols of the communication frame, where higher priority application data bits are placed into bit positions with greater or equal levels of protection than bit positions into which lower priority application data bits are placed. The communication frame may then be transmitted to one or more receivers with an indication of how to decode the placement of the application data bits within the symbols. In another embodiment, the particular constellation map may be dynamically selected from a plurality of available constellation maps, such as based on communication channel conditions and/or applications generating the data.

摘要： A set of data symbols is selected from a set of modulation constellation, and a sample-mean of the set of data symbols is determined. Each data symbol is first shifted by the sample-mean to obtain a shifted data symbol, and then the shifted symbol is multiplied by a first constant to obtain a scaled data symbol. A second constant is added to the scaled data symbol to obtain a mapped data symbol. The sample-mean is multiplied by a third constant to obtain a sample-mean mapped symbol. The set of mapped data symbols and the sample-mean mapped symbol are then transmitted as a resource block.
