Abstract

In the Orthogonal Frequency Division Multiplexing (OFDM) system, a channel estimation algorithm based on least squares (LS) and forward error correction (FEC) iteration was proposed for the shortcoming of traditional LS algorithm. In this paper, LS algorithm and FEC algorithm were introduced, and the improved algorithm was explained in detail. The improved algorithm used the FEC correction performance to correct channel estimation results. Simulation results showed that the improved algorithm can effectively improve the performance of channel estimation.
