METHOD AND APPARATUS FOR PARALLEL MIDAMBLE CANCELLATION

METHOD AND APPARATUS FOR PARALLEL MIDAMBLE CANCELLATION

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...

description 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. ® KIPO & WIPO 2009
