CHANNEL ESTIMATE DEVICE AND CHANNEL ESTIMATE METHOD FOR INVERSE EQUALIZATION

摘要

PROBLEM TO BE SOLVED: To enhance the reception characteristic of a transmitter-receiver to be inversely equalized even when the reception level of an advancing wave is remarkably smaller than the reception level of a delayed wave and the noise level is furthermore smaller than the reception level of the advancing wave.;SOLUTION: A noise generator 102 generates noise data denoting the white Gaussian noise, a noise adder 101 sums received data and the noise data, and an inverse equalization channel estimate unit 103 disables estimation of an advancing wave whose level is a level of the noise data or below from the data after summing.;COPYRIGHT: (C)2002,JPO
