摘要:
A correlation signal generating circuit generates a duplicate signal for correlation processing based on a multiplex duplication signal. An autocorrelation circuit performs autocorrelation processing through sliding processing of the duplicate signal with respect to a received signal. An Nd detecting circuit detects the length of the data symbol by detecting a correlation value peak obtained based on the guard interval symbols. A data correlation circuit performs mutual correlation processing on the extracted data through the sliding processing by changing the window sizes. An Ng detecting circuit detects the length of the guard interval symbol by detecting the correlation value peak which is obtained when the guard interval symbol length and the window size become consistent.
