A head-end equipment associated with a communication system configured to interface with an interference group (IG) composed of two or more modems is disclosed. The head-end equipment comprises a memory configured to store a plurality of instructions; and one or more processors configured to retrieve the plurality of instructions from the memory. In some embodiments, the one or more processors, upon execution of the plurality of instructions from the memory, is configured to generate an advanced warning signal to be provided to one or more modems associated with the IG. In some embodiments, the advanced warning signal comprises an information that a select modem, different from the one or more modems, in the IG will be initiating an upstream communication in a select frequency band, as well as information on a start time and a duration of the upstream communication.

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.

Configurable constellation mapping to control spectral efficiency versus signal-to-noise ratio

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.

Signaling method for interference group discovery in cable modems

Symbols are received on a downstream channel. A value of a channel synchronization parameter is determined based on the received symbols. An interference event on the downstream channel is detected. In response to detecting the interference event: an output signal is determined based on at least one cached value of the channel synchronization parameter, the at least one cached value being determined based on symbols received prior to and offset from the detecting of the interference event.
