<P>PROBLEM TO BE SOLVED: To monitor the line quality degradation of a mobile communication system by a relatively small-scale circuit, to suppress line quality decline, and to contribute to the reduction of power consumption as well, with respect to a wireless receiver of digital wireless communication. <P>SOLUTION: The wireless receiver has a delay detection demodulation circuit and an equalization demodulation circuit, wherein propagation path conditions such as multipath generation conditions are predicted from the error rate of the synchronization words of the output signal strings of the two demodulation circuits, a reception input level and the soft determination value by the delay detection demodulation circuit, and the two circuits are switched and used. <P>COPYRIGHT: (C)2010,JPO&INPIT |
