A digital radio receiver is adapted to receive radio signals modulated using continuous phase modulation. The receiver includes components for receiving analogue radio signals having various carrier frequencies and a plurality of correlators corresponding to different bit sequences. Each of the plurality of correlators share a common estimator for estimating a frequency offset between the radio signals carrier frequencies and nominal carrier frequencies. The receiver further includes components allowing the estimator to determine which of the correlators produce the most optimal output signal.

A method and an apparatus are provided for improving a carrier to noise density ratio (CNO) of a matched filter. A signal is received at a signal register of the matched filter. A local code is received at a local code register and a nulling register of the matched filter. An adder tree of the matched filter correlates the signal register and the local code register with respect to the nulling register to obtain a correlation result. The nulling register prevents high frequency samples of the signal register from affecting the correlation result.

Provided is a method of processing a WCDMA signal timing offset for a signal analyzer. The method includes estimating an integer multiple timing offset of WCDMA baseband sample data corresponding to an amount of at least one frame; generating a frequency domain signal which is time delayed corresponding to a fractional timing offset estimation resolution after generating the frequency domain signal by performing an FFT calculation on an already-known reference signal; converting each time-delayed frequency domain signal into a time domain signal by performing an IFFT calculation on each time-delayed frequency domain signal and calculating a correlation between an input signal from a position of the integer multiple timing offset and the time domain signal; and estimating a delay time leading to a maximum correlation as a fractional timing offset.
