Patent ID: 7372897

Claim:
A portable information communication terminal, comprising: correlation detecting means for detecting correlation of a received base band signal and a reference code sequence; averaging means for averaging an output of said correlation detecting means; path detecting means for detecting a path of the received base band signal in accordance with the output of said averaging means; first reception state measuring means for measuring a reception state of a simultaneous received signal simultaneously received along with the received base band signal; averaging operation controlling means having first distribution position estimating means for estimating a distribution of correlation values at a timing of which a path exists in accordance with the reception state of the simultaneous received signal, and being configured for controlling a number of times for an averaging operation by said averaging means in accordance with an output of said first distribution estimating means; assigned number-of-paths determining means for determining whether or not the number of paths to which the simultaneous received signal is assigned reaches an upper limit of paths that can be assigned; and wherein said first distribution position estimating means is configured to measure a reception state of a path of which the simultaneous received signal is (i) in a maximum level when the assigned number of paths does not reach the upper limit, and (ii) in a minimum level when the assigned number of paths reaches the upper limit.
