Abstract :
In this paper, we design a cooperative wavelet scheme for the multi-relay, multi-scale and multi-lag diversity, which can be widely applied in the ultra-wideband communications and underwater acoustic communications. A Decode-and-Forward (DF) cooperative relay network is set for the multi-scale and multi-lag wideband channels. Then, an analytical bit error rate (BER) expression for this DF cooperative wavelet wideband communication system is proposed, which can be used to predict the system performance. Based on the proposed analytical BER expression, we also provide a dynamic optimal selection strategy for relay selection to take advantage of the multi-relay, multi-scale and multi-lag diversity and maximize the system BER performance.
