Research on configurable Rake receiver based on software defined radio

多模混合基站是新一代无线通信系统的重要特征,而软件无线电架构是实现多模式基站的重要方法。主要研究在软件无线电平台中,根据多径信道的延迟特性,利用信道估计算法的可重配置,提高Rake接收机性能。对多种信道下的可配置Rake接收进行了仿真,结果表明,可配置Rake接收算法可以提高系统在复杂多径信道下的性能。

Multi-mode station is the important character of the new generation of wireless communication system.The software defined radio（SDR） is an important method to implement multi-mode station.According to delay character of multipath channel,this paper uses the configurable channel estimation algorithm to achieve the better performance of Rake receiver based on SDR.The simulation of configurable Rake receiver under many channels shows that the algorithm can improve the performance of complex multipath channel.
