<p><P>PROBLEM TO BE SOLVED: To provide communication equipment for highly precisely detecting the peak of the correlation value of a signal whose spectrum spread modulation has been operated and a diffusion code. <P>SOLUTION: This communication equipment is provided with correlators (113I, 113Q, 115I, 115Q) for receiving input of a signal whose spectrum spread modulation has been operated by a spreading code, and for calculating the correlation value of the input signal and the spreading code by symbol units; a first peak detector (118) for detecting the peak of the correlation value; arithmetic units (123I, 123Q, 125I, 125Q) for integrating a plurality of symbols by inverting the positive and negative codes of the correlation value when the peak is detected according to a slot pattern; and a second peak detector (128) for detecting the peak of the integrated correlation value. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
