Abstract: A first transceiver operable to establish a connection with a second transceiver over a channel. A receiver of the first transceiver maintains communication parameters for the connection with the second transceiver, and processes signals received over the channel according to the communication parameters. The receiver monitors for idle frames from the second transceiver, and begins running of a first idle period in response to detecting a predetermined number of consecutive idle frames. The receiver, during the first idle period, suspends adaptation of the communication parameters. At an end of the first idle period, the receiver receives a first frame from the second transceiver, selectively adapts the communication parameters based on the first frame, and selectively begins running of a second idle period. A transmitter of the first transceiver suspends transmitting frames to the second transceiver during the first idle period and the second idle period.

Abstract: A system includes converters, first modules, second modules, and a multiplexer. The converters receive an analog signal and a respective one of multiple clock signals. Each of the converters samples the analog signal based on a respective clock signal to generate a respective digital signal. Each of the clock signals is out-of-phase with other ones of the clock signals. The first modules receive the digital signals generated by the converters, remove bias offsets from the digital signals to generate first output signals, and output each of the first output signals on a multiple channels. The second modules receive the first output signals, and based on the first output signals, remove or equalize gain mismatch between the channels to generate second output signals. The multiplexer receives the second output signals, and generates an output based on the second output signals. The output is a digital representation of the analog signal.

Abstract: A cancellation system is disclosed for processing incoming and outgoing signals in a transform domain to create a cancellation signal for reducing or removing unwanted interference. Data is ordered based on Good-Thomas indexing into a two dimensional array in a buffer. The two dimensional array may have lr rows and lw columns. From the buffer, the columns of data undergo a Winograd small transform. The rows of data undergo a Cooley-Tukey operation to complete the transform operation into the frequency domain. Multipliers scale the transformed data to generate a cancellation signal in the frequency domain. Inverse (Cooley-Tukey) and Winograd transforms perform inverse processing on the cancellation signal to return the cancellation signal or data to the time domain. Re-ordering the data and combination of the cancellation signal or data with incoming or outgoing signals achieve interference cancellation.
