  • Method for a receiver unit to determine a quality value for a received signal
    Patent number: 6002715
    Abstract: A received signal (310) includes information symbols ("D's") including equidistant symbols that are equidistant from the origin of a complex plane. The D's and corresponding interference signals ("I's") are formed (403) and the quantity of equidistant symbols determined (407). A desired signal portion average is based (409) on the received signal. When the quantity of equidistant symbols exceeds a threshold, an undesired signal portion average is based (413) exclusively on the I's corresponding to the equidistant symbols. Otherwise, the undesired signal portion average is based (423) on the I's corresponding to all received D's, including the equidistant symbols. A received signal quality value is then based on a ratio of the desired signal portion average and the undesired signal portion average.
