Abstract

Method and apparatus for performing midamble cancellation (14) to remove midamble interference from the convolution tail of data field (I) and the first W-1 chips of the midamble field which results from the delay spread of the multipath channel and for cancelling the first W-1 chip midamble spread in the data field (II), which are performed substantially simultaneously. The received burst, typical a TDD burst, is stored, the midamble interference and the corresponding parts in the received burst are removed and the resulting burst is applied to a multi-user detector (20) to obtain the symbol sequences.
