A signal receiving apparatus for receiving signals is provided. The signal receiving apparatus includes a correlation-value computation section configured to sequentially compute a correlation value representing a correlation between the received signal and a series of known symbols while sliding the series of known symbols for every symbol included in the received signal, a maximum-value detection section configured to detect a largest correlation value among the correlation values computed by the correlation-value computation section for one frame of the received signal, and a correlation-value storage section configured to store each of the correlation values at one of a predetermined number of storage locations, before and after the largest correlation value is detected by the maximum-value detection section.
