| 摘 要： | 介绍了空时分组编码技术.利用TD-SCDMA系统特殊的帧结构,提出了空时分组编码技术与TD-SCDMA系统结合的两种方案.即在发送端以一个突发中的数据域为单位进行空时分组码的编码,接收端采用一根或两根天线接收,对一个突发中两个数据域同时进行译码.由于采用发送分集技术,仿真结果证明它可以显著提高TD-SCDMA系统性能.

| Abstract: | This paper tells of the space-time coding technology. And by utilizing the especial frame structure of TD-SCDMA system, two schemes in combination of space-time coding technology and the TD-SCDMA system are proposed. In the transmission side, the data based on data field of a burst is encoded, while in the receiver side, is received and the data through one or two antenna and the two data fields decoded simultaneously. Due to the adoption of transmit diversity technology, the simulation results prove that i... |
