We propose a data precoded relay-assisted scheme, for a system cooperating with L relays, each one equipped with a single antenna. The use of relays is of significant interest to allow radio access in situations where either the direct path is not available or has poor quality. However because of the half duplex constraint at the relays, transmission of a data rate that would be possible using a modulation...
In the present wireless scenario, transmit diversity has become one of the key contributing technologies. Analytical estimations of bit error rate (BER) can be obtained with space time transmit diversity (STTD). The desired user's BER performance improves as fading of interfering signal decreases. Nakagami-m fading is becoming more prevalent in performance analysis and other studies related to mobile...
