  • In wcdma system which uses direct sequence to spread spectrum , the spread spectrum code ( pn code ) phase of the receiver must be synchronized with that of the received signal precisely to despread and demodulate the signal correctly . multipath channel exists in the mobile communication environment for the radio signal reflection by obstacles between transmitters and receivers . by using the autocorrelation of the spread sprectrum code , rake receiver can process received signals and therefore multipath components can be resolvable
    在wcdma系统中,为正确解扩解调接收到的扩频信号,接收机本地产生的扩频码( pn码)相位必须和接收信号中的扩频码相位完全同步;同时移动通信环境中的传输信号由于接收机和发射机之间的直达路径有可能被建筑物或其他障碍物所阻碍,总是经过折射或反射的多条路径后才到达接收机,从而产生多径信道。
