| Abstract: | In this paper,an algorithm is proposed for blind detection and parameter estimation of OFDM signals based on Cyclic Prefix.This algorithm can utilize the correlation of cyclic prefix of received signals to obtain the blind detection of OFDM signal,and the parameter estimation for OFDM is obtained by finding the peak value of the combined correlation function.The algorithm can distinguish OFDM signals from the others,and it can be widely used.Experiment results show that the proposed algorithm has a high det... |
