OFDM is really a multicarrier transmission which has been widely applied in wireless communication systems due to its high bandwidth efficiency, its simple implementation and robustness over frequency selective channel. In this context, this paper aims to explain joint iterative channel estimation with symbol detection for coded orthogonal frequency division multiplexing. In this paper, the style of a second order Kalman filtering technique for fast fading channels based on pilot symbol aided modulation (PSAM) was created. Nevertheless, as the fading percentage increases, extra pilot symbols have to obtain completely correct channel estimates for reliable data detection. This decreases the complete data rate during fast fading to unacceptable levels for many applications. The suggested algorithm's performance is tested in a simulated wireless OFDM system sent across a radio channel based on our research and discussions. In order to enhance the overall performance of PSAM, it's essential to exploit iterative channel estimation as well as symbol detection strategy.
