摘要: 該文分析了應用于CDMA Ad hoc網(wǎng)絡的TRBC(Transmitter and Receiver Based Coding)協(xié)議，其性能同傳統(tǒng)的TBC(Transmitter Based Coding)和RBC(Receiver Based Coding)協(xié)議進行了比較。數(shù)值結果分析表明，由于TRBC協(xié)議采用兩級編解碼，在帶寬充足或用戶數(shù)量較小的環(huán)境下，其性能高于RBC協(xié)議，低于TBC協(xié)議。但是其系統(tǒng)復雜度也高于RBC協(xié)議，低于TBC協(xié)議。因此，TRBC協(xié)議作為性能與系統(tǒng)復雜度的一種權衡，對于設計可行的CDMA Ad hoc網(wǎng)絡，具有重要意義。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.
