Iterative Equalization and Source Decoding for Vector Quantized Sources
, 2006 In this contribution an iterative (turbo) channel equalization and source decoding scheme is considered. In our investigations the source is modelled as a Gaussian-Markov source, which is compressed with the aid of vector quantization. The communications

Impact of Spectrum Sharing on the Efficiency of Faster-Than-Nyquist Signaling
, 2014 Capacity computations are presented for Faster-Than-Nyquist (FTN) signaling in the presence of interference from neighboring frequency bands. It is shown that Shannon's sinc pulses maximize the spectral efficiency for a multi-access channel, where ...

Joint Effects of Synchronization Errors of OFDM Systems in Doubly-Selective Fading Channels
EURASIP Journal on Advances in Signal Processing, 2009 The majority of existing analyses on synchronization errors consider only partial synchronization error factors. In contrast, this work simultaneously analyzes joint effects of major synchronization errors, including the symbol time offset (STO), carrier

A metric to quantify the time-varying characteristics of underwater acoustic communication channels [PDF]
JASA Express LettersUnderwater acoustic communication signals suffer from time dispersion due to time-varying multipath propagation in the ocean. This leads to intersymbol interference, which in turn degrades the performance of the communication system.

Information Rates of Energy Harvesting Communications With Intersymbol Interference
IEEE Communications Letters, 2019 We consider energy harvesting communications over an intersymbol interference (ISI) channel corrupted by additive white Gaussian noise. We assume that the energy arrivals at the transmitter, which is equipped with a finite battery, are independent and identically distributed, and provide a method of computing achievable information rates with channel ...

Extending the impulse response in order to reduce errors due to impulse noise and signal fading [PDF]
A finite impulse response (FIR) digital smearing filter was designed to produce maximum intersymbol interference and maximum extension of the impulse response of the signal in a noiseless binary channel.
