A New Application of Correlator in Future Wireless Telecommunication Systems

This paper presents a new method to use correlator in modern communications after analysing the application and performance of the traditional correlator in detail. According to the results of simulation, the new method have more precise frequency and timing synchronization in wireless communications, which improves its ability against interference of multipath and frequency selective fading. Even in the circumstances of low signal to noise ratio (SNR: 0 dB), it also has a very high accuracy of synchronization.
