Near-Instantaneously Adaptive Cooperative Schemes based on Space-Time Block Codes and V-BLAST

El-Hajjar, M., Zummo, S. and Hanzo, L. (2007) Near-Instantaneously Adaptive Cooperative Schemes based on Space-Time Block Codes and V-BLAST At IEEE VTC'07 (Spring). 22 - 25 Apr 2007. , pp. 2200-2204.

Record type: Conference or Workshop Item (Paper)


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.
