In a radio reception apparatus, a quadrature detector provides its digital
output signal to a band-limiting filter after lowering a sampling
frequency by a sampling frequency converter. Based on a correlation value
obtained from an output of the band-limiting filter by a symbol timing
detecting circuit, a symbol timing deviation detecting circuit detects a
magnitude and a direction of a deviation of the timing of sampling in the
sampling frequency converter, and controls timing of the sampling in the
sampling frequency converter. Thereby, a symbol point of the correct
timing is extracted.
