ABSTRACT:
A method and apparatus (400) manages a current data symbol received by a receiver (122) in a frame of data of a time diversity communication system (102, 104). A symbol counter (402) counts a signal (404) from a symbol clock synchronized to the frame of data to provide a count of the current data symbol, and a bit line translator (416) maps a current address from the count. A conditional processor (434) derives a selected memory address from the current address. Then, based upon the current address, a comparator (424) makes a choice among (a) storing the current data symbol in a memory at the selected memory address, (b) merging the current data symbol with an earlier received data symbol stored at the selected memory address during an earlier frame of data, and (c) ignoring the current data symbol.
