基于Matlab的CDMA RAKE接收机性能仿真
CDMA RAKE receiver performance simulation based on Matlab
摘要
Abstract
Since the CDMA mobile communication system is affected by the building and landform,its communication envi⁃ronment is very complex,and its communication quality are badly affected. CDMA system using RAKE receiving technology can distinguish the subtle multipath signal in time,and can take advantage of the multipath signal to overcome the effects of multipath fading and enhance the reception capacity. Based on the basic theory analysis of RAKE receiver,Matlab simulation software is adopted to perform performance simulation of RAKE receiver under different user states. Three combining modes of maximum ratio, gain,selection are compared. The simulation results and bit error rate performance parameters are given. The performance of the RAKE receiver in the CDMA system is modeled and simulated. The simulation results show that RAKE receiver used in CDMA system can play a role of anti⁃multipath interference,and can improve system performance.关键词
