%X The low-complexity Least Square (LS) channel estimation in Orthogonal Frequency Division Multiplexing (OFDM) is studied in this paper. To reduce the error floor of OFDM with LS channel estimation, the diversity reception and turbo product coding are used in system design. The simulation results show that the turbo product coding and diversity combining can reduce the error floor in seriously frequency-selective channel. The gap of the OFDM system with LS channel estimation and with channel state information is only 4dB.
