A block demodulator with an automatic equalizer is proposed. A new complex block equalizer that uses a direct algorithm based on the minimum-mean-square-error criterion is utilized to make the most of the block demodulation. The speed of convergence can be increased by changing the number of taps in the automatic equalizer. Computer simulation shows that the proposed system has superior performance compared with the conventional block demodulators. For example, the mean square error of the data in the proposed block demodulator becomes 1/100 of that in the conventional system at SNR = 30 dB.
