ABSTRACT:
Disclosed is a receiver for achieving optimum power consumption and optimum reception performance according to use, purpose, and required performance. A control circuit calculates an evaluation value H relating to a detection method and a reception state of a received signal. When a delay detection is selected depending on the evaluation value H, a delay detection circuit and a judgment circuit operate, and a selection circuit selects and outputs an output signal of the judgment circuit. When a semi-synchronous detection is selected depending on the evaluation value H, the semi-synchronous detection circuit, the signal judgment unit and the differential decoder operate, and the selection circuit selects and outputs an output signal of the differential decoder. When a dynamic controlled detection is selected depending on the evaluation value H, the delay detection and the semi-synchronous detection are controlled to be dynamically changed.
