Vacant channel searching method |
摘要 |
<p>There is provided a vacant channel searching method for use in a wireless communication system, capable of finding a optimum vacant channel which is under least influence of the disturbance by taking also into account the periodicity and burst properties of disturbance waves. The short-term fluctuation (short cycle T1) of disturbance waves is observed over each observation interval length T2. Through repetitive observations up to a repetition number N, the long-term fluctuation (long cycle T3) of the disturbance waves is observed. As a result, constant observations of disturbance generation are realized in such a manner as to account for the periodicity and burst properties of the disturbance waves. By determining a channel which is under least influence of the disturbance based on the results of such observations, it becomes possible to find an optimum vacant channel. <IMAGE></p> |
