Free registration required

Executive Summary

In this paper, the performance of Bit-Interleaved Coded Modulation-Iterative Decoding (BICM-ID) based cooperative network is analyzed over Rayleigh, Nakagami-m and Rician fading channels. In this system coding diversity is obtained through BICM and spatial diversity through cooperative relaying network. The analysis is performed for the relays operating in both Amplify-and-Forward (AF) and Decode-and-Forward (DF) modes. The Bit Error Rate (BER) bound of multiple-relay cooperative system with the serial concatenated BICM-ID using the Set Partitioning (SP) and Gray Mapped (GM) labeling for M-ary Phase Shift Keying (M-PSK) modulations over Nakagami-m fading channels is obtained.
