中文摘要：

在多基站协作传输中，由于发射天线分布在不同基站而导致接收信号具有内在的时间异步特性。基于现有MIMO系统同步环境下应用的正交空时分组码，提出了能适应多基站协作环境的一种异步空时分组码构造方法，并给出了相应的宽带OSTFDM—MIMO系统发射端编码结构和接收端译码实现。该系统在多基站协作传输中对信号异步传输具有鲁棒性，较传统的其它系统结构能提供更高的空间分集度和更高的数据传输速率，但同时不会增加系统接收机的译码复杂度。

英文摘要：

The design method of asynchronyous resilient space -time block codes（STBCs） applied in multiple base stations coordination transmission system with distributed antennas is proposed, and then encoding implementation in transmitter and decoding structures in receiver for wideband OSTFDM - MIMO system are discussed. Finally, system performances are analyzed. Compared with some conventional methods, this system can encode over groups of distributed transmit antennas, and provide added space diversity and higher date rates without increasing the decoder complexity.
