Channel quality assessment method and system for performing the same

摘要

A channel quality assessment with short assessment time and good frequency resolution is disclosed. Some channels are grouped and their detecting results are collected as whale to determine the channel quality. The channel quality is determined by interference collision ratio, which is the ratio of the number of interference events to the sum of the number of interference events and interference-free events. Interfered channels are disabled form the group. The Channel quality of each of plurality of channels is determined from detection results of each of plurality of groups so as to have a short assessment time and meanwhile a good frequency resolution may be retained.
