trellis code-aided high-rate M-QAM space-time labeling diversity using a unitary expansion
收藏 引用
INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS 2018年 第11期31卷 e3590-e3590页
作者: Dlodlo, Buthanani Xu, Hongjun Univ KwaZulu Natal Sch Engn ZA-4041 Durban South Africa Zhejiang Gongshang Univ Sch Informat & Elect Engn Hangzhou Zhejiang Peoples R China
In this paper, we present a high-rate M-ary quadrature amplitude modulation (M-QAM) space-time labeling diversity (STLD) system that retains the robust error performance of the conventional STLD system. The high-rate ... 详细信息

Performance bound and trellis-code design criterion for discrete memoryless channels and finite-delay symbol-by-symbol decoding
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 1997年 第10期45卷 1192-1199页
作者: Baccarelli, E Cusani, R DiBlasio, G Department of INFOCOM University of Roma La Sapienza Rome Italy
A new tight analytical upper bound is presented for the performance of finite-delay symbol-by-symbol (SBS) Abend-Fritchman-like decoding of trellis-encoded data crossing arbitrary (eventually time-varying) discrete me... 详细信息

ELECTRONICS LETTERS 2000年 第3期36卷 217-218页
作者: Martin, I Honary, B Univ Lancaster Commun Res Ctr Lancaster LA1 4YR England
A novel code combining system based on Reed-Muller codes is presented. Because of their simple structure RM codes are simple to decode using a trellis based soft maximum likelihood decoder (SMLD). The decoder exploits... 详细信息

IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCES 2016年 第8期E99A卷 1618-1621页
作者: Zhang, Chao Ma, Lu Tsinghua Univ Sch Aerosp Engn Labs Avion Beijing 100084 Peoples R China
trellis coded modulation (TCM) concept is applied to the mode constellation points of orbital angular momentum (OAM) modulation. OAM modulation considers the multiple OAM modes as additional constellation points and m... 详细信息

Error rate performance of trellis coded PR4ML system for digital magnetic recording channel with partial erasure
收藏 引用
IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCES 1998年 第10期E81A卷 2159-2165页
作者: Saito, H Takai, M Okamoto, Y Osawa, H Ehime Univ Fac Engn Matsuyama Ehime 7908577 Japan
In general, the performance of partial response maximum-likelihood (PRML) system is degraded by nonlinear distortion and high frequency noise in high-density digital magnetic recording. Conventional PRML system For si... 详细信息
