Abstract:
Bit-error-rate (BER) performance of coded cooperative networks with selection decode-and-forward (S-DF) relaying is analyzed over the Nakagami-m fading channels. Previously, in the literature, BER analysis was done only for the un-coded network, where an impractical symbol-based forwarding is employed. In this paper, we analyze the bit-interleaved code modulation (BICM) coded cooperative network with an easy-to-implement packet-based forwarding. In particular, a closed-form BER expression is derived for the S-DF with source re-transmission (S-DF/RT) relaying, where the source re-transmits the packet to the destination on behave of a relay if it fails to decode. The accuracy of the proposed analysis is confirmed by computer simulations.
