Abstract :
An innovative and successful design for channel estimation in the orthogonal frequency division multiplexing (OFDM) system is presented. The method joints channel state information (CSI) estimation and decoding with the proportional-integral-differential (PID) controller and wavelet decomposition. Also, PID controller is discussed. In addition, the performance of this method and the comparison between this method and the traditional one in different channels are given.
