1. A channel determination method in a carrier sensing operation performing a signal receiving operation while switching between reception frequencies of a receiving section, the method comprising:

  • determining whether or not electric field strength of a received signal exceeds a predetermined threshold;

    detecting a predetermined preamble in received data during the carrier sensing operation;

    determining to enable or disable a channel in which the predetermined preamble is detected in the received data, in accordance with the electric field strength of the signal;

    causing a counter to count up when the electric field strength of the received signal exceeds a predetermined threshold and causing the counter to count down when the electric field strength of the received signal does not exceed the predetermined threshold for each channel during the carrier sensing operation; and

    disabling each channel when the count value of the counter of a corresponding one of the channels reaches a predetermined value.
