Proposition of a phase difference detector for the correlation receiver

This article proposes a new method of maintaining synchronization of carrier for the correlation receiver. We use PSK of fifth phase for this telecommunication system. However, we can apply this method for the correlation receiver of any other demodulation. As usual method for the synchronization, there is DLL (Delay Lock Loop). However we thought that we can directly find the value of phase difference, and we can modify carrier of the receiver. Therefore in this article we suggest a method to detect the phase difference and we evaluate performances. We verified the limit of detected phase difference in the strong noise and in the interference of one's own code. We used kinetic threshold for detection, We could flexibly detect the phase difference for any quantity environment. The result, showed that with S/N=-3dB and with interferences using two PN-codes, we verified that the phase difference is detected when it's higher than 0.69 (rad). We also explain the principle of the method by mathematic demonstration, simulation and improvement of PN-code length. At last, we compare our method to the method of DLL. We conclude that this method has good performances as the DLL.
