Bit-interleaved coded modulation with iterative decoding
Xiaodong Li,James A. Ritcey +1 more
TL;DR: A simple iterative decoding technique using hard-decision feedback is presented for bit-interleaved coded modulation (BICM), making BICM with iterative decode suitable for both types of channels.
Journal ArticleDOI
Bit-interleaved coded modulation with iterative decoding and 8 PSK signaling
TL;DR: It is shown that at high signal to noise ratios, the performance of BICM-ID converges to the performance assuming error-free feedback, and the analytical bounds on the performance with an ideal feedback assumption are provided.
Journal ArticleDOI
Design, analysis, and performance evaluation for BICM-ID with square QAM constellations in Rayleigh fading channels
A. Chindapol,James A. Ritcey +1 more
TL;DR: This work proposes the design criteria that utilize a large Hamming distance inherited in a low-rate code and a new labeling technique designed specifically for fading channels that results in a large coding gain over noniterative coded modulation and performance close to that of "turbo" coded modulation with less complexity.
Journal ArticleDOI
Underwater acoustic communication by passive-phase conjugation: theory and experimental results
Daniel Rouseff,Darrell R. Jackson,Warren L. J. Fox,Christopher D. Jones,James A. Ritcey,David R. Dowling +5 more
TL;DR: In this article, a new method for coherent underwater acoustic communication called passive phase conjugation (SPC) is evaluated. But unlike active phase conjuplication, SPC requires only receive signals.
Journal ArticleDOI
Trellis-coded modulation with bit interleaving and iterative decoding
Xiaodong Li,James A. Ritcey +1 more
TL;DR: It is shown that convolutional codes with good Hamming-distance property can provide both high diversity order and large free Euclidean distance for BICM-ID, which provides a simple mechanism for variable-rate transmission.
