<P>PROBLEM TO BE SOLVED: To provide a multicarrier modulation signal receiver which can maximally extract effects of error correction without including errors in a detection value of interference signal quantity. <P>SOLUTION: A signal is received by an antenna part and processing performed in a conventional receiver such as orthogonal detection processing, FET processing, equalization processing, de-interleave processing, demapping processing, decoding processing, energy inverse spread processing, and Reed-Solomon decoding processing, are performed. A signal to be input to a demapping processing part (symbol point after equalization) is stored separately, while encoding processing is performed to data rows of Reed-Solomon decoding result in the same procedure as that of modulation processing in a transmitter, again. At that time, energy spread processing, convolutional encoding processing and mapping processing for multi-value modulation QAM signal such as QPSK, 16QAM, and 64QAM, are performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
