Genetically Optimized Pre coders Transceiver Design for Double STBC System
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2014, Vol 2, Issue 8
Abstract
Wireless communications depends on multiple-inputmultiple-output (MIMO) techniques for high data rates. Feedback of channel information can be used in precoding to use the strongest channel mode and improve MIMO performance. The DPC system is interference free on multi-user or multi-antenna. The STBC transceiver can provide the transmit diversity. Due to the benefits about the STBC and DPC system, we propose a new scheme called STBC-DPC system. The transceiver design involves the following procedures. First, the ordering QR decomposition of channel matrix and the maximum likelihood (ML) one-dimensional searching algorithm are proposed to acquire a reliable performance. Next, the channel on/off assignment using water filling algorithm is proposed to overcome the deep fading channel problem. Finally, the STBC-DPC system with the modulus operation to limit the transmit signal level, i.e., TomlinsonHarashima precoding (THP) scheme, is proposed to retain low peak-to-average power ratio (PAPR) performance. Simulation results confirm that the proposed STBCDPC/THP with water filling ML algorithm can provide the low PAPR and excellent bit error rate (BER) performances.
