The cooperative relaying technique enables a terminal to get space-diversity through the support of other terminals. However, existing cooperative relaying techniques for code division multiple access (CDMA) system decrease the total system transmission rate. In this letter, a new relaying technique is presented which supplies lossless transmission-rate using 2 spreading codes per terminal. We verify the performance of the proposed technique through a bit error rate (BER) simulation for a direct-sequence ultra wideband (DS-UWB) system. It is also shown that forward error correction (FEC) coding provides a better environment for the cooperative relaying.
