本文研究了一种基于交织复用（ＩＤＭ）的分布式空时编码方案，对一种适用于该方案的迭代接收机结构进行性能分析。同时通过仿真，对所提出的协作编码方案进行性能评估。在相似环境下，通过比较本方案与其它协作空时码的性能，表明本方案由于采用了非正交的空时编码，具有多方面的优越性。同时它还可以采用灵活的发送天线数配置，反映到协作通信的场景，也就是对中继终端的数量没有特殊要求。

A distributed spacetime coding scheme based on Interleaving Division Multiplexing (IDM) is investigated. The performance of an iterative receiver structure for the proposed scheme over a quasistatic channel is analyzed.The performance of the proposed scheme is evaluated via simulation, and its advantages are shown by comparison to other spacetime schemes in similar settings.This scheme is able to achieve high spectrum efficiency with a low complexity, and provides high flexibility on the number of cooperating nodes, while no strict synchronization is required among them. 
