Zusammenfassung:Method and apparatus for performing midamble cancellation to remove midamble interference from the convolution tail of data field and the first W−1 chips of the midamble field which results from the delay spread of the multipath channel and for canceling the first W−1 chip midamble spread in the data field , which operations are performed substantially simultaneously. The received burst, typically a TDD burst, is stored, the midamble interference and the corresponding parts in the received burst is removed and the resulting burst is applied to a multi-user detector to obtain the symbol sequences.
