IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS 2002年 第2期1卷 226-235页
作者: Catreux, S Driessen, PF Greenstein, LJ Iospan Wireless San Jose CA 95131 USA Univ Victoria Victoria BC V8W 5C3 Canada AT&T Labs Res Middletown NJ 07748 USA
We present a general framework to quantify the data throughput capabilities of a wireless communication system when it combines: 1) multiple transmit signals;2) adaptive modulation for each signal;and 3) adaptive arra... 详细信息

International Conference on Wireless Networks, Communications and Mobile Computing
作者: Hamouda, W Concordia Univ Dept Elect & Comp Engn Montreal PQ HEG 1M8 Canada
In this paper, a transmit diversity scheme based on space-time spreading for code-division multiple-access (CDMA) systems in fast-fading channels is introduced. The proposed transmit diversity scheme employs orthogona... 详细信息

International Conference on Wireless Communications, Networking and Mobile Computing
作者: He, YJ Zhu, GX Zhang, BJ Zhang, ZM Li, X Huazhong Univ Sci & Technol Dept Elect & Informat Engn Wuhan 430074 Peoples R China
Space-Time Block Codes(STBCs) are designed to obtain the full diversity gain. However, STBCs are not designed to achieve an additional coding gain. Therefore, STBCs need to be concatenated with an outer code which pro... 详细信息
