Abstract 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.
