<p>PROBLEM TO BE SOLVED: To provide a receiving device which can provide information about more reception states in addition to information about whether or not the quality of a signal is enough.SOLUTION: A receiving device 1 includes: a channel selection processing part 5 which performs channel selection processing of a received signal; a CN ratio detection part 9 for detecting CN ratio of the received signal; an RFAGC circuit part 7 for generating RFAGC voltage to control signal gain before the channel selection processing; an IFAGC circuit part 8 which controls signal gain after the channel selection processing; a control unit 11 for detecting the RFAGC voltage and IFAGC voltage; and a Packet error detection part 10 for detecting error information from a signal after the channel selection processing. On the basis of at least either the RFAGC voltage, the IFAGC voltage, or the error information, and the CN ratio, a reception state of the signal is examined.</p> |
