摘要： A method for jointly designing a transmitter pulse-shaping filter (36) and a receiver pulse-shaping filter (68) having respective filter coefficients includes defining one or more performance-related variables based on at least some of the filter coefficients of the transmitter and receiver pulse-shaping filters.

摘要： A transmitter may map, using a selected modulation constellation, each of C' bit sequences to a respective one of C' symbols, where C' is a number greater than one. The transmitter may process the C' symbols to generate C' inter-carrier correlated virtual subcarrier values. The transmitter may decimate the C virtual subcarrier values down to C physical subcarrier values, C being a number less than C'. The transmitter may transmit the C physical subcarrier values on C orthogonal frequency division multiplexed (OFDM) subcarriers. The modulation constellation may be an N-QAM constellation, where N is an integer. The processing may comprise filtering the C' symbols using an array of C' filter tap coefficients. The filtering may comprise cyclic filtering. The filtering may comprise multiplication by a circulant matrix populated with the C' filter tap coefficients.

摘要： A sequence estimation circuit may be operable to receive a sample of a received inter-symbol correlated (ISC) signal corresponding to a transmitted vector of symbols, wherein each of the symbols is one of a plurality of symbols in a particular constellation. The sequence estimation circuit may be operable to generate an estimate of the transmitted vector of symbols using a reduced state sequence estimation (RSSE) process. Each iteration of the RSSE process may comprise generating a plurality of candidate vectors. A first element of each of the candidate vectors may hold a respective one of the plurality symbols in the particular constellation. The first element may be an estimate of a symbol of the transmitted vector of symbols other than a most-recent symbol of the transmitted vector of symbols. A second element of each of said candidate vectors holds a respective one of a plurality of calculated filler values.

摘要： A receiver may be operable to generate estimates of transmitted symbols using a sequence estimation process that may incorporate a non-linear model. The non-linear model may be adapted by the receiver based on particular communication information that may be indicative of non-linearity experienced by the transmitted symbols. The receiver may generate a reconstructed signal from the estimates of the transmitted symbols. The receiver may adapt the non-linear model based on values of an error signal generated from the reconstructed signal, and the values of the error signal may be generated from a portion of the generated estimates that may correspond to known symbols and/or information symbols. The values of the error signal corresponding to the known symbols may be given more weight in an adaptation algorithm, and the values of the error signal corresponding to the information symbols may be given less weight in the adaptation algorithm.

摘要： Circuitry for use in a receiver may comprise: a front-end circuit operable to receive an orthogonal frequency division multiplexing (OFDM) symbol on a first number of physical subcarriers. The circuitry may comprise a decoding circuit operable to decode the OFDM symbol using an inter-carrier interference (ICI) model, the decoding resulting in a determination of a sequence of symbols, comprising a second number of symbols, that most-likely correspond to the received OFDM symbol, where the second number is greater than the first number. The sequence of symbols may comprise N- QAM symbols, N being an integer. The ISCI model may be based, at least in part, on non-linearity experienced by the OFDM symbol during transmission by a transmitter, propagation over a channel, and/or reception by the receiver. The ISCI model may be based, at least in part, on phase-noise introduced to the OFDM symbol during transmission by a transmitter, propagation over a channel, and/or reception by the receiver.
