摘要:
由于在第三代移动通信系统CDMA中传输的信号带宽较宽,许多复杂的多径无线信号存在于该系统中,导致通信的质量受到影响。RAKE接收技术作为CDMA系统中重要的能够克服多径衰落的分集接收技术,能够在时间上分辨出来自不同方向的多径无线信号,并且能够将分辨出来的多径信号分别进行延时和相位校正、使之复合成加强的信号。文中在分析RAKE接收技术原理和应用的基础上,通过SystemView仿真软件仿真实现了系统中信号的调制解调和接收,并结合其原理对仿真结果进行分析,得出以下结论：通过仿真图的比较,在多径信道中,RAKE接收机得到的信号优于常规方法恢复出的信号
Abstract:
Due to the wider bandwidth of the signal transmitted in the third generation mobile communication system of CDMA, exist many complex multipath radio signals,influencing the communication quality. RAKE receiving technology as an important diversity re-ceiving technology in the CDMA system can overcome the multipath fading,can in time tell a multipath wireless signals from different di-rections,and can conduct time delay and phase correction for the multipath signals which are composite to strengthen the signal. On the basis of analyzing the RAKE reception technology principle and application,has realized the RAKE reception through the SystemView simulation software simulation,and unifies its principle to carry on the analysis to the simulation result. Get the conclusions that compari-son of the simulation map,RAKE reception signal is better than the one-path ones in multipath fading channel
