摘要：

In this paper, we derive the optimal power to be allocated to source and relays in cooperative DS-CDMA systems. The study is valid for any channel. The analysis is carried for dual-hop and multihop systems in the presence of an arbitrary number of DF relays. A significant performance enhancement (2 dB) is observed when the proposed power allocation strategy is performed with respect to uniform power allocation. Our results are new since they take into account multipath propagation between different nodes whereas previous studies are valid for a single path channel.
