PROBLEM TO BE SOLVED: To improve call quality and to reduce power consumption by making the respective local oscillation part frequencies on an idle carrier side and a use carrier side to be similar and executing four-input synthesis diversity reception through the use of an idle carrier side receiver function when traffic quantity is less and an input electric field value is low. SOLUTION: A CPU part 9 designates a LOCAL part 4b with a CH designation signal in a way similar to a LOCAL part 4a. A carrier B side and an A side, which a received wave contains, are set to same LOCAL frequencies and the frequencies of the LOCAL parts 4a and 4b become same. The CPU part 9 gives an instruction for transmitting decoding data after error correction to an error correction part 7 to error correction parts 6a and 6b, makes the error correction part 7 in a standby state, error-corrects decoding data from the error correction parts 6a and 6b, corrects the errors twice, strongly corrects the errors and outputs data to a transmission path part 8 as decoding data after synthesis. Thus, a bit error rate equal to a four-input synthesis diversity reception circuit can be improved. |
