摘要 该文分析了应用于CDMA Ad hoc网络的TRBC(Transmitter and Receiver Based Coding)协议,其性能同传统的TBC(Transmitter Based Coding)和RBC(Receiver Based Coding)协议进行了比较。数值结果分析表明,由于TRBC 协议采用两级编解码,在带宽充足或用户数量较小的环境下,其性能高于RBC协议,低于TBC协议。但是其系统复杂度也高于RBC协议,低于TBC协议。因此,TRBC协议作为性能与系统复杂度的一种权衡,对于设计可行的 CDMA Ad hoc网络,具有重要意义。 The TRBC （Transmitter and Receiver Based Coding） protocol adopted in CDMA Ad hoc networks is analyzed in this paper, its performance is compared with the traditional TBC （Transmitter Based Coding） and RBC （Receiver Based Coding） protocols. The analysis of numerical results indicates that the performance of TRBC protocol using two levels of encoding and decoding is better than that of RBC protocol, and worse than that of TBC protocol under the environments with enough bandwidth or a small quantity of users. However, its system complexity is also more than that of RBC protocol, and less than that of TBC protocol. Therefore, as a trade-off between performance and system complexity, the TRBC protocol has great significance for the designing of a practical CDMA Ad hoc networks.
