A view on full-diversity modulus-preserving rate-one linear space-time block codes
收藏 引用
SIGNAL PROCESSING 2006年 第8期86卷 1968-1975页
作者: Zhou, Shengli Ma, Xiaoli Pattipati, Krishna Univ Connecticut Dept Elect & Comp Engn Storrs CT 06269 USA Auburn Univ Dept Elect & Comp Engn Auburn AL 36849 USA
In this paper, we consider the class of linear space time block codes (STBCs) that possess the following properties: (i) enabling full antenna diversity, (ii) preserving the modulus of information symbols, and (iii) a... 详细信息

IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCES 2005年 第11期E88A卷 3203-3213页
作者: Zhang, H Li, W Gulliver, TA Univ Victoria Dept Elect & Comp Engn Victoria BC V8W 3P6 Canada
In this paper, the capacity and error probability of orthogonal space-time block codes (STBCs) are presented for PAM/PSK/QAM modulation in correlated flat fading channels. We consider an equivalent scalar AWGN (additi... 详细信息

Tap-constrained constant modulus algorithm for the blind equalisation of time-reversal-based STBCs through the exploitation of algebraic properties
收藏 引用
IEE PROCEEDINGS-COMMUNICATIONS 2005年 第3期152卷 295-301页
作者: Luo, Y Lambotharan, S Kings Coll London Ctr DSP Res London WC2R 2LS England
A tap-constrained constant modulus algorithm is proposed for the blind equalisation of a time-reversal-based space-time block-coded (STBC) transmission. The tap constraint has been developed by exploiting certain alge... 详细信息

IEEE Wireless Communications and Networking Conference
作者: Xian, L Liu, HP Oregon State Univ Sch Elect Engn & Comp Sci Corvallis OR 97331 USA
Receive diversity yields a higher signal-to-noise ratio (SNR) than transmit diversity when the total transmitted power and diversity order are the same. However, if the transmitter has complete or partial knowledge of... 详细信息

2005年无线通信、网络和移动计算国际会议
作者: Jianxin Guo Lei Jiang Yanxin Gou Xiangru Meng Telecommunication Engineering Institute Air Force Engineering University Xi'an China
In this paper, a blind channel estimator, which is based on linear non-redundant precoding and second-order statistics, is proposed for space time block (STBC) coded MIMO-OFDM systems. According to the complex orthogo... 详细信息
