ABSTRACT:
A signal vector obtained by synchronous detection of a received signal is sampled by a sampling rate equal to a symbol rate. The sampled signal vector is rotated by a predetermined angle, and a mean value vector is calculated by latest rotated signal vectors of the number corresponding to a length of a particular signal sequence to be detected. Then, a square and summation value between the mean value and the rotated signal vector used for calculating the mean value vector is calculated. When the square and summation value becomes less than a predetermined value, a particular signal sequence is assumed to be detected.
