<p>A radio receiver (10) for receiving a signal is provided. The radio receiver (10) comprises an equalizer (22) configured to perform a constant modulus algorithm initialized using a first set of coefficients on the received signal and for generating an equalized signal (23). The radio receiver (10) further comprises a demodulator (24) coupled to the equalizer (22) for demodulating the equalized signal (23). The radio receiver (10) further comprises a lowpass filter (30) coupled to the demodulator (24) for lowpass filtering the demodulated signal to detect a spurious signal and to generate an offset signal (31). The radio receiver (10) further comprises a coefficient generator (32) coupled to the lowpass filter (30) and configured to compare the offset signal (31) to a predetermined threshold, and if the offset signal (31) satisfies a predetermined condition in relation to the predetermined threshold, then to generate a second set of coefficients for re-initializing the constant modulus algorithm.</p> |
