<p>PROBLEM TO BE SOLVED: To provide a wireless communication device capable of receiving a wireless signal of a direct wave frequency in the state of the device being stand by to receive a wireless signal of a base station wave frequency.SOLUTION: In a wireless communication device incorporating only one series of reception system, a frequency of a receiver is switched to a direct wave [f3] by 0th frame, 6th frame and 12th frame of a communication system in which 18 frames constitutes 1 super-frame so that these three frames constitute a period for measuring a reception level of the direct wave [f3] and constitute a period for determining whether the reception level of the direct wave is equal to or higher than a given level. If determined that the reception level of the direct wave [f3] in this period is less than the given level, the first-5th, 7th-11th, and 13th-17th frames become periods for standing by to receive a base station wave [f2], the period in which the base station wave [f2] can be received. As the direct wave [f3] in the periods of 0th frame, 6th frame and 12th frame is determined to have a level that is receivable, an operation is transitioned to receive the direct wave [f3].</p> |
