Patent ID: 7428278

Claim:
A method for parallel midamble cancellation in a received Time Division Duplex (TDD) burst, having first and second data fields separated by a midamble field, for canceling the effect of midamble interference on the second data field of the received burst, comprising: a) storing the received burst; b) determining a channel estimation from a midamble portion of the received burst; c) utilizing the channel estimation for obtaining channel responses and midamble shift numbers; d) converting the midamble shift numbers to midamble codes; e) constructing a first midamble interference sequence based on associated pairs of said channel responses and midamble codes to provide a first midamble interference corresponding to a given number of chips of a tail of the received midamble field into the second data field and subtracting the first midamble interference from the second data field of the data burst for canceling the effect of midamble interference on the second data field.
