Efficient Channel Shortening Equalizer Computation
Channel shortening is often necessary for demodulation of multicarrier signals, complexity reduction of maximum likelihood sequence estimation (MLSE), and can be used to suppress interference in multiuser detection. The Maximum Shortening SNR (MSSNR) and Minimum Mean Squared Error (MMSE) designs for channel shortening are popular in the literature due to their ease of implementation and near-op...
متن کاملEfficient Channel Shortening Equalizer Design
Time-domain equalization is crucial in reducing channel state dimension in maximum likelihood sequence estimation, and inter-carrier and inter-symbol interference in multicarrier systems. A time-domain equalizer (TEQ) placed in cascade with the channel produces an effective impulse response that is shorter than the channel impulse response. This paper analyzes two TEQ design methods amenable to...
متن کاملExploiting symmetry in channel shortening equalizers
Time-domain equalization is crucial in reducing inter-carrier and inter-symbol interference in multicarrier systems. A channel shortening time-domain equalizer (TEQ), which is a finite impulse response (FIR) filter, placed in cascade with the channel produces an effective impulse response that is shorter than the channel impulse response. We show that finite length minimum mean squared error (M...
متن کاملOptimum channel shortening for discrete multitone transceivers
We propose an optimum channel shortening method for discrete multitone (DMT) transceivers. The proposed method shortens a given channel to a desired length while maximizing the number of bits transmitted on a DMT symbol. The key to the optimum solution is the de nition of the SNR in a subchannel using the equivalent signal, noise, and ISI paths in the system. Our simulation results show that th...
متن کاملFast Channel Shortening with Polynomial Weighting Functions
Channel shortening is often necessary for demodulation of multicarrier signals and complexity reduction of maximum likelihood sequence estimation (MLSE). This paper has two parts: (i) the proposal of complexity-reduction techniques for channel shortening designs with polynomial weighting functions, including the minimum inter-block interference (Min-IBI) and minimum delay spread (MDS) designs, ...
