This paper considers the problem of channel coding over Gaussian intersymbol interference (ISI) channels with a given metric decoding rule. Specifically, it is assumed that the mismatched decoder has an incorrect assumption on the impulse response function. The mismatch capacity is the highest achievable rate for a given decoding rule. Existing lower bounds to the mismatch capacity for channels...

A humongous development in the study of Nyquist filter has been observed in the recent years. This paper presents a review of the work done on a Nyquist filter in the last decade. Nyquist filter is called M th band filter because it has zero coeffient at every M th sample except its middle coefficient. Different filter methods have been proposed with the focus of improving filter parameters lik...

An algorithm that performs joint equalization and decoding for nonlinear two-dimensional intersymbol interference channels is presented. The algorithm performs sum-product message-passing on a factor graph that represents the underlying system. The two-dimensional optical storage (TWODOS) technology is an example of a system with nonlinear two-dimensional intersymbol interference. Simulations f...

This report provides an introduction to the problem of analyzing the performance of satellite on-board regenerative repeaters. Two speci c group demodulator architectures are discussed: one based on a polyphase network followed by an FFT processor, and the other based on a chirp Fourier transform implemented using surface acoustic wave (SAW) devices. Due to imperfect ltering and channel separat...

Calderbank, Heegard, and Ozarow [l] have suggested a method of designing codes for channels with intersymbol interference, such as the magnetic recording channel. These codes are designed to exploit intersymhol interference. The standard method is to minimize intersymbol interference by constraining the input to the channel using run-length limited sequences. Calderbank, Heegard, and Ozarow con...

In this contribution we present a new family of soft equalizers for multiple input multiple output (MIMO) systems with frequency selective fading. The proposed equalizers are based on soft successive interference cancellation (SIC) of both intersymbol interference (ISI) and multiple antenna interference (MAI), and are applicable to both single user MIMO systems with ISI and MIMO multipath chann...
