Abstract: PROBLEM TO BE SOLVED: To restrict a fact that a unique word cannot be detected by a fluctuation of a correlating value caused by a level fluctuation of a receiving signal. SOLUTION: This receiver comprises the same amplitude component ratio as a ratio of an amplitude component of a receiving signal r(t) (real component: Re [r(t)] and imaginary component: Im [r(t)]), acquires an amplitude adjusting signal u(t) that an amplitude value is a predetermined magnitude (e.g. 1), and acquires a correlating value of this amplitude adjusting signal u(t) and a unique word. More specifically, the amplitude adjusting signal u(t) comprises a phase θ(t) of the receiving signal r(t) acquired from the amplitude components Re [r(t)], Im [r(t)], and acquires a signal u(t) of an amplitude of 1, i.e., as u(t)= cos(θ)+j.sin(θ) (j: imaginary number). As using the signal u(t) adjusted to be a fixed amplitude, it is possible to acquire more reliably the correlating value not depending on a fluctuation of the receiving signal r(t).
