Description/Abstract

In this paper we propose two adaptive schemes for improving the achievable throughput of cooperative diversity aided wireless networks. These schemes are capable of accommodating the channel signal-to-noise ratio (SNR) variation of wireless systems by near-instantaneously adapting the uplink transmission configuration. Explicitly, the first adaptive transmission scheme is constituted by a novel reconfigurable multilayered space-time block code (MLSTBC) structure. By contrast, the second adaptive scheme is constituted by a reconfigurable vertical Bell Labs Layered Space Time (VBLAST)-like architecture. Our results demonstrate that significant effective throughput improvements can be achieved by both systems, while maintaining a target bit-error-ratio of 10?3. Explicitly, the first system is capable of attaining an effective throughput varying between 1 bit-per-symbol (BPS) and 8 BPS, while the second has a throughput varying between 2 BPS and 8 BPS.
