摘要

提出了一种MIMO CDMA系统中的STBC方案。在该方案中,输入符号被分割成块,每个块有M个符号(M为发射天线的个数),M个符号被循环编码成M组(每组有M个循环符号),编码后的M × M个符号分别乘M个扩频码通过Mantennas以M个符号持续时间传输。提出的STBC方案具有全编码率(码率1)和全分集顺序,但解码方法与Alamouti[1]引入的传统STBC一样简单。

A Novel STBC Scheme in MIMO CDMA System
A novel STBC scheme in MIMO CDMA system is presented. In the proposed scheme, the input symbols are split in blocks, each block has M symbols (M is the number of transmitting antennas), the M symbols are circularly encoded into M groups (each group has M cyclic symbols), the encoded M × M symbols are transmitted in Msymbol durations through Mantennas by multiplying M spread-codes respectively. The proposed STBC scheme has full coding rate (rate 1) and full diversity order but the decoding method is as simple as the conventional STBC introduced by Alamouti [1].
