英文摘要：
The estimation method of phase difference between multi-path signals and the elimination technique of loss factor caused by non-coherent demodulation are investigated firstly. With the phase difference estimation method, a non-coherent demodulation Rake receiver implementation scheme is proposed, in which the loss factor caused by non-coherent demodulation is eliminated in base band. By using the presented estimation method of phase difference, we can not only eliminate the impact of the loss factor in base band, but also realize the perfect coherent demodulation in radio frequency. The performance analysis shows that the presented scheme is effective.
