Design and performance evaluation of cooperative hybrid CDD scheme in OFDMA uplink network

[摘要] References(6)In recent years, cooperative communication has been widely investigated to improve performance of wireless communication networks based on Orthogonal frequency division multiple access (OFDMA). Cooperative communication is applied to single-antenna system at the destination. However, in the OFDMA uplink network, the base station (BS) is simply equipped with multiple antennas. Therefore, cooperative diversity and multiplexing schemes can be easily applied in the BS with multiple antennas. In this letter, to guarantee reliability with high throughput simultaneously, we propose a cooperative hybrid cyclic delay diversity (CDD) scheme which can use an arbitrary number of relays without rate loss and a modification of the BS although the number of relays is changed.
