<p>Disclosed are a communication apparatus which performs multichannel transmission by executing preprocessing for searching for an adequate channel for communications from a plurality of channels (CH1-CHN) assigned to a radio frequency band and then setting a normal communication state, and a communication method for use in such a communication apparatus. The communication apparatus comprises a control section (16) for generating an instruction signal (S1, S2) for tuning to frequencies of channel candidates and one or more frequencies in the vicinity of the frequencies of the channel candidates; a reception section (1; 2, 3) having a specific selection characteristic, for tuning to the frequencies of the channel candidates (CH1-CHN) and the one or more frequencies in the vicinity of the frequencies of the channel candidates (CH1-CHN) in accordance with the instruction signal (S1, S2); a measuring section (13, 15) for measuring a reception strength (RSSI) of a signal (Sx) produced from a received signal by the reception section (1; 2, 3); and a decision section (15, 16, 17) for determining whether or not received signals of the channel candidates (CH1-CHN) are adequate for communications based on reception strengths (RSSI) of the received signals. <IMAGE></p> |
