RADIO RECEPTION APPARATUS, SYMBOL TIMING CONTROL METHOD, AND SYMBOL TIMING CONTROL PROGRAM

摘要

In a radio reception apparatus, a digital output signal of an orthogonal detector (4) is reduced in sampling frequency by a sampling frequency converter (15) and given to a band limit filter (6). According to a correlation value obtained by a symbol timing detector circuit (17) from the output of the band limit filter (6), a symbol timing shift detector circuit (18) detects a timing shift size and direction of sampling in the sampling frequency converter (15) and adjusts the sampling timing in the sampling frequency converter (15). Thus, a symbol point of a correct timing can be extracted.
