Claim:
A channel quality assessment method for a communication system having a plurality of channels for receiving signal packet traffic utilizing a plurality of received signal, comprising the steps of: (a.1) grouping said plurality of channels into a plurality of groups, each of said plurality of groups having at least one channel; and (a.2) determining a channel quality of each of said plurality of channels responsive to detection results of the received signals in each of the plurality of groups; comprising steps of: (a.2.1) defining a quality assessing operator responsive to said plurality of receiving signals for determining qualifies of said plurality of channels and said plurality of groups containing said plurality of channels; (a.2.2) determining a quality assessing value of a first selective group from said quality assessing operator; wherein if a quality assessing value of said first selective group is not within a predetermined range, said first selective group is an unqualified group, if a second selective group is overlapped with said unqualified group, arid a size of said unqualified group is smaller than that of said selective group, then overlapping channels between said unqualified group and said second selective group are disabled in said second selective group, the size of said second selective group being reduced by the number of said overlapping channels; (a.2.3) determining a quality assessing value of a selective channel being the qualified assessing value of said first selective group that satisfies the follow conditions that (a.2.3.1) said selective group containing said selective channel, and said selective channel being not disabled in said selective group; and (a.2.3.2) said selective group has a largest number of non-disabled channels.
