Patent ID: 7440507

Claim:
A transceiver configured to estimate a channel in a communication system, the transceiver comprising: a receiver portion for receiving a block of “n” transmitted symbols, the symbols including “p” pilot symbols and “d” data symbols, where “p” is an integer having a value greater than or equal to 1, “d” is an integer having a value greater than or equal to 2 and “n” is an integer having a value greater than or equal to 3; an estimator for estimating a channel using the pilot symbols; a processor for choosing a group of “m” strongest symbols from the “d” received data symbols, where “m” is an integer having a value less than or equal to d, and for compensating the group “m” strongest symbols using the channel estimate to create a group of “m” compensated symbols; and wherein the estimator re-estimates the channel using the group of “m” compensated symbols and pilot symbols, and either: the processor repeats choosing the group of “m” strongest symbols, compensates the group of “m” strongest symbols to re-estimate the channel; or the processor uses a latest channel estimate to compensate all symbols within the block.
