| 摘 要： | 线性预编码提高了多天线UWB系统的传输速率和误码率性能。通过选择合适的参数,系统最大限度地达到最大吞吐量,而多天线技术提高了系统空间分集增益。针对传统的ZF算法限制误码率性能提高的问题,提出了一种新的预编码方案,实现简单。仿真结果表明,新算法进一步减小系统误码率,提高了系统性能,较传统的ZF算法性能更为优越。

| Abstract: | Linear precoding improves the transmission rate and bit error rate for multi-antenna UWB system.The maximum reachable throughput of the system can be achieved by using the optimal parameters,and the multi-antenna mechanism provides full spatial diversity gain.Because the improvement of the bit error rate performance is limited for the ZF algorithm,a new precoding scheme is proposed and it is easy to implement.The simulation results show that the new algorithm reduces the system mean BER and consequently improves the system performance. |
