| Abstract: | 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. |
