Time-frequency differential encoding and detection for cyclic prefix assisted CDMA system

A new differential encoding and detection scheme for cyclic prefix assisted CDMA system was proposed.Considering the correlation between channel impulse response in both time domain and frequency domain,a time-frequency differential encoding scheme and corresponding noncoherent detection and equaliz...

description A new differential encoding and detection scheme for cyclic prefix assisted CDMA system was proposed.Considering the correlation between channel impulse response in both time domain and frequency domain,a time-frequency differential encoding scheme and corresponding noncoherent detection and equalization based on MMSE criterion were presented.Computer simulation results show that it outperforms conventional method in fast fading multipath channel significantly,and shows high robustness against Doppler spread.
