Patent ID: 8743987

Claim:
A receiver configured to perform symbol detection, comprising: a plurality of receive antennas operable to receive a frequency domain signal comprising a block of time domain symbols; electronic circuitry operable to: divide the block of time domain symbols in the received signal into plural sub-blocks; for each sub-block, perform a joint detection of the symbols of the sub-block while during the joint detection treating symbols of the block that are outside of the sub-block as noise; generate plural joint hypotheses for the time domain symbols in the sub-block; perform an evaluation of a decision metric for each of the plural joint hypotheses and to detect correct symbols based on the evaluation of the decision metric; determine separately for each subcarrier of the block, a combining weight that is applicable for all the sub-blocks of the block; and use the combining weight to perform the evaluation of the decision metric for each subcarrier of the sub-block.
