Multipath Selection Method for Maximum Ratio Combining in Underwater Acoustic Channels

초록

This paper proposes a multipath selection method for maximum ratio combining to improve bit error rate (BER) performance in code division multiple access (CDMA) experiencing underwater long multi-path channels. To select optimum paths, BERs are calculated for each multipath and the optimum multipaths that exhibit the minimum BER are selected. Computer simulation shown that the proposed method has better BER performance than a conventional threshold generalized selective combining (T-GSC).
