PURPOSE:To reject the interference between codes, by using time axis equalizer used of MSE method or HYB method as the equalizer of transversal or discrimination feedback type. CONSTITUTION:A peak value of an output signal of an adder 5 is detected at a peak voltage detection circuit 10 and the gain of a variable gain circuit 2 is controlled by a controlling circuit 11. Further, the result of correlation between the output signal of an adder 5 and the signal delayed with delaying circuits 61-6N is obtained with correlation devices 7a-7N, and the peak voltage detected is input to controlling circuits 101-10N. Further, the output signal of the adder is input to emphasis circuits 91-9N. The output of the emphasis circuit 9N is input to the time axis equalizer 20 applying MSE method or HYB method. The output of the time axis equalizer 20 is also input to the controlling circuits 101-10N, which control the emphasis circuits 91-9N. |
