A novel adaptive Turbo equalization algorithm based on the serious inter-symbol interference (ISI) in wireless channel is proposed. The channel characteristics are estimated through combining iterative recursive least square (RLS) with least mean square(LMS) and channel´s changes are traced; and the soft interference cancellation (SIC) algorithm for Turbo equalization and the iterative calculations between equalizer and decoder are employed. Simulation results show that adaptive Turbo equalization achieves nearly 1.5 dB gain at 10-4 of BER compared with the conventional RLS, and reduces the complexity of calculation.
