摘　　要：给出了一种适用于TD-SCDMA系统的多媒体广播/组播(MBMS)业务下行接收检测算法。这种检测算法通过对多个小区的数据在Chip级进行合并,一方面可以避免TDD模式下MBMS广播业务之间的同频干扰问题;另外,可以利用Chip级合并提供处理增益。因此该方法可以使多个小区在一个时隙中发送高速的MBMS业务,有较高系统利用率。MBMS（Multimedia Broadcast/Multicast Service） is basically a new broadcast and multicast radio bearer technology. MBMS can providing high speed downlink, non-voice services for multiple users simultaneously in full area coverage. A novel algorithm named chip level combination method applied to MBMS in TD-SCDMA system is presented. This method can effectively avoid co-frequence interference and provide process gain. So it is possible to transmit high speed rate data in multi-cell simultaneously with best system utilization ratio.
