ABSTRACT:
A radio communication system receiver employs a demodulator (104) to recover a received signal. The receiver of the present invention further includes a channel quality estimator (222) for estimating a characteristic of the communication channel over which the signal is received. A first or second decoding technique (220) is selectively employed using the estimated communication channel quality value (223). In this manner, an improved receiver is provided that is able to realize the benefits of either the first or the second decoding technique, depending the channel condition.
