Multipath interference removal method and multi-path interference removing apparatus

摘要

In replica generator 109, I want to create a replica of the four-pass # path and # 3 on the effectiveness symbol A. The arithmetic unit 111 convolution, by convolving the impulse response to a replica of the path # 4 and # 3 path, to determine the interference portion. This interference portion is output to the subtraction unit 104. In the subtracting unit 104, the interference portion is subtracted from the next OFDM symbol. That is, to obtain the interference portion with the effective symbol A, is subtracted from the effective symbol B (portion leaking range to perform an FFT of the effective symbol B) the interference portion. Thus, I can prevent the distortion occurs in the effective symbol B.
