An iterative optimization method of transmit/receive frequency domain equalization (FDE) is proposed for single carrier transmission systems, where both transmit and receive FDE weights are iteratively determined with a recursive algorithm so as to minimize the error signal at a virtual receiver. The computer simulation results show that SC systems using the proposed transmit/receive equalization method achieves better BER performance than those using the conventional receive FDE. BER performance of SC systems using the proposed method was improved by about 2.7dB at BER=10-3 compared to case of those using conventional receive FDE in attenuated 6-path quasistatic Rayleigh fading with normalized delay spread value of τ/T = 0.769. In addition, when decision feedback equalizer (DFE) with sufficient number of feedback taps is adopted in both systems, the proposed system achieves better BER performance than the conventional system in a low Eb/N region and BER performance of the proposed system becomes close to that of the conventional one as Eb/N0 increases in the above channel condition.
