摘要
在基于串行干扰抵消的Rake接收机的基础上作了改进,提出了一种新的Rake接收机结构,对其进行了原理和性能分析,给出了Matlab仿真结果,并与基于串行干扰抵消的Rake接收机性能进行了比较。仿真结果表明,改进的基于串行干扰抵消的Rake接收机性能明显得到提高,同时减小了误码率。
Multipath effect is one of the major influence to communication performance. For the purpose to remove the multiprth interference, a modified Rake receiver which is based on serial interference cancellation method is proposed in this paper. Principles and performances are analysed. And Matlab simulation tests are carried out. Last, performances of the modified Rake reciver and the Rake receiver which based on serial interference cancellation are compared. The simulation result indicates that the Rake receiver performance is improved apparently.
