Abstract:
1. An apparatus for retrieving information of an information channel of a plurality of different information channels from a received transmit sequence, the received transmit sequence being generated using different code sequences for the information channels of the plurality of different information channels and using different candidate channel sequences for at least one information channel of the plurality of different information channels, comprising: an extractor for extracting a candidate channel sequence corresponding to the information channel of the plurality of different information channels from the received transmit sequence, wherein properties of the extractor are defined by a code sequence associated with the information channel of the plurality of different information channels; and a processor for processing the candidate channel sequence to determine the information for the information channel of the plurality of different information channels, wherein the processor is arranged such that a processing of information performed when generating the candidate channel sequence is inverted.
