Abstract: Mixed mode constellation mapping to map a data block to a block of sub-carriers based on a configurable set of one or more constellation mapping schemes, and corresponding mixed mode least likelihood ratio (LLR) de-mapping based on the configurable set of one or more modulation schemes. The set may be configurable to include multiple modulation schemes to provide to a SEvSNR measure that is a non-weighted or weighted average of SEvSNR measures of the multiple modulation schemes. Mixed mode constellation mapping may be useful be configurable to control spectral efficiency versus SNR (SEvSNR) over a range of SNR with relatively fine SNR granularity, and may be configurable to control SEvSNR over a range of SNR at a fixed FEC code rate, which may include a highest available or highest permitted code rate.

Abstract: A cable modem system for discovering interference groups (IGs) includes an infrastructure and a cable modem termination system (CMTS). The infrastructure is for transferring data. The CMTS is configured to initiate generation of test signals by a set of cable modems (CMs), obtain a set of test measurements for the set of CMs, discover interference groups (IGs) of the set of CMs based on the obtained set of test measurements and assign a plurality of upstream and downstream channels for the set of CMs that use orthogonal frequency division multiplexing (OFDM) based on the discovered IGs.

Abstract: A method and apparatus for cancelling self-interference in a cable network implementing full duplex (FDX). A processor in a cable modem may obtain a frequency response of an echo channel for at least one sub-channel in an FDX band and calculate filter coefficients based on the frequency response, and an interference canceller cancels the self-interference in the downstream signal. The interference canceller includes filters in a digital domain to generate an interference cancellation signal from a reference signal. In another example, the processor may obtain frequency responses of an echo channel for all sub-channels in a FDX band, combine the frequency responses for the FDX band, and generate a channel impulse response for the FDX band from the combined frequency response. The interference canceller may then cancel the self-interference in the downstream signal in an analog domain based on the channel impulse response.

Abstract: Some demonstrative embodiments include devices, systems and methods of multi-channel processing. For example, a multi-channel data processor may process data of a plurality of channels, the multi-channel data processor is to switch from processing a first channel to processing a second channel of the plurality of channels by performing a context switch during a single clock cycle, the context switch including storing first state context corresponding to a processing state of the first channel and loading previously stored second state context corresponding to a processing state of the second channel.
