摘要： The invention includes a full duplex transceiver for transmitting and receiving communication signals. The transceiver includes 1 to N sample and hold circuits. Each sample and hold circuit receives a first signal that includes a far-end signal, and in some cases an echo signal, and in some cases alternatively or additionally cross-talk signals. The transceiver additionally includes a plurality of subtraction circuits. Each subtraction circuit receives an output of at least one of the sample and hold circuits. Each subtraction circuit subtracts at least a fraction of a replica signal from at least a fraction of the output of the at least one of the sample and hold circuits. The subtraction circuits generate an output that represent the far-end signal with substantially reduced echo and/or cross-talk interference, and is available for additional receiver processing.

摘要： A device and method of high-speed transmission is disclosed. The method includes computing a signal quality of a received signal, the received signal being transmitted with a modulation order required by a default transmission modulation format. The signal quality is compared with a signal quality threshold required of the default transmission modulation format. If the signal quality is below the signal quality threshold, an indication of a level of signal quality failure is provided to a transmitter. The transmitter sets a number of un-coded bits within the transmission signal based upon the level of signal quality failure.

摘要： A method and apparatus of joint processing a plurality of digital signal streams is disclosed. The method includes transforming a plurality of the digital signal streams from an original domain to a lower complexity processing domain. The transformed plurality of digital signal streams are joint processed, wherein the joint processing includes multiplying samples of the plurality of transformed digital signal streams by a processing matrix. The joint processed signal streams are inverse transformed back to the original domain. Diagonal elements of the processing matrix are adaptively selected to cancel transmission echo signals of the plurality digital signal streams introduced during transmission of the plurality digital signal streams depending upon signal coupling of the plurality of digital signal streams.
