An important accomplishment of information theory is the determination of the channel
capacity, C, which quantifies the maximum achievable transmission rate, C∗, of a system …

We investigate turbo equalization, or iterative equalization and decoding, as a receiver
technology for systems where data is protected by an error-correcting code, shuffled by an …

The soft-input soft-output (SISO) module is the basic building block for established iterative
detection (ID) algorithms for a system consisting of a network of finite state machines. The …

This paper presents a new fractionally-spaced maximum a posteriori (MAP) equalizer for
data transmission over frequency-selective fading channels. The technique is applicable to …

We propose a novel soft-input soft-output equalizer for single-carrier transmissions over
unknown frequency-selective block-fading channels. Our equalizer leverages the recently …

To combat the effect of intersymbol interference (ISI) while transmitting data over an ISI
channel in a coded data transmission system, the impulse response of the channel is …

The problem of sequence detection in frequency-nonselective/time-selective fading
channels, when channel state information (CSI) is not available at the transmitter and …

The underwater acoustic channel belongs to a class of stochastic communication channels
that are frequency-and, at long range, energy-limited and doubly spread. The primary …

High frequency (HF) radio communications offer latency advantages over fiber-optics in
certain long-distance communication applications. As a result, there is interest in using HF …

In a receiver employing turbo equalization for an unknown, time-varying, frequency-selective
channel, the channel estimate can be improved for each iteration by using soft information …
