It is an object of the present invention to downsize a receiver of a mobile phone, its base station and the like. In the invention, a level measurement circuit 15 a, a frequency offset detection circuit 16 a, a frequency correction circuit 17 a, a channel skewness detection circuit 18 a, a channel skewness correction circuit 19 a, and a maximum ratio synthesis circuit 3 a are constructed by CORDICs 153, 171, 182, 191, 31 to 3 M, and 200 . Further, the level measurement circuit 15 a and the frequency offset detection circuit 16 a share the CORDIC 153 with each other.
