The research is done of OFDM-TDM blind equalization algorithm in fast fading environment. Interpolation and DD-LMS and MCMA algorithm is introduced, which is also applied in blind decision feedback equalizer's tap update. Then a more applicable frequency selective fading environment and better performance DD-LMS+MCMBDFE algorithm is obtained. This algorithm has better balance and can automatically compensate phase error and doppler frequency offset error, with faster convergence speed and smaller residual error after convergence. The simulation results show that the interpolation DD-LMS+MCMBDFE algorithm is an effective blind decision feedback equalization algorithm.
