Performance of multicarrier DS CDMA systems
TLDR
We apply a multicarrier signaling technique to a direct-sequence CDMA system, where a data sequence multiplied by a spreading sequence modulates multiple carriers, rather than a single carrier. Expand

Theory of Spread-Spectrum Communications - A Tutorial
TLDR
We provide a tutorial treatment of the theory of spread-spectrum communications, including a discussion on the applications referred to above, on the properties of common spreading sequences, and on techniques that can be used for acquisition and tracking. Expand

Capacity-approaching bandwidth-efficient coded modulation schemes based on low-density parity-check codes
TLDR
We design multilevel coding (MLC) and bit-interleaved coded modulation (BICM) schemes based on low-density parity-check (LDPC) codes. Expand

Performance analysis and code optimization of low density parity-check codes on Rayleigh fading channels
TLDR
A numerical method has been presented to determine the noise thresholds of low density parity-check codes that employ the message passing decoding algorithm on the additive white Gaussian noise (AWGN) channel. Expand

On the performance of hybrid FEC/ARQ systems using rate compatible punctured turbo (RCPT) codes
TLDR
This paper introduces a hybrid forward-error correction/automatic repeat-request (ARQ) system that employs rate compatible punctured turbo (RCPT) codes to achieve enhanced throughput performance over a nonstationary Gaussian channel. Expand

Interference rejection techniques in spread spectrum communications
It is argued that the ability of a spread-spectrum system to withstand interference, both intentional and unintentional, is probably its greatest asset. Any spread spectrum receiver can only suppressExpand

A noise-whitening approach to multiple access noise rejection .I. Theory and background
TLDR
In this paper, receivers that maximize signal-to-noise ratio in a DS-CDMA system model under various constraints are proposed and analyzed. Expand
