Abstract
A communication system (200) employs a method and apparatus for performing diversity voting in the communication system. A comparator (206) receives a signal frame (207-209) of code words from each of multiple signal sources (202-204). A prioritized code word of each signal frame occupies a corresponding frame position and has a respective signal quality metric associated therewith. The comparator determines whether each signal quality metric accurately represents the signal quality of its respective prioritized code word. When the signal quality metrics do not accurately represent the signal qualities of their respective prioritized code words, the comparator determines a supplemental signal quality metric for each prioritized code word. The comparator then selects one prioritized code word from all the corresponding prioritized code words based on a comparison of the supplemental signal quality metrics for input into the corresponding frame position of a voted signal frame (330).
