1. A channel assignment method for multi-FA (Frequency Assignment) CDMA cellular systems in which a base station communicates a plurality of mobile stations, comprising the steps of:

  • comparing a first threshold value with variance of received power when the base station receives a new call request;

    assigning a traffic channel in a first FA of the request, if the variance of received power is less than the first threshold value, and searching a second FA of which variance of received power is least, if not;

    comparing a second threshold value with the variance of received power; and

    assigning a traffic channel in the second FA if the variance of received power is less than the second threshold value, and rejecting the request, if not.
