Abstract:
1. A method for receiving communications in time frames comprising a plurality of time slots, said time slots having data signals for a plurality of channels, comprising: decoding, by a code detector, using a blind cod technique data signals in the timeslots to determine the identity of the plurality of channels when the identity of all channels is not known; detecting midambles to provide a set of channelization codes and their associated midambles shifts for a candidate code list; generating the candidate code list including identified own-UE candidate codes and other-UE candidate codes from the plurality of channels; comparing the identified own-UE and other-UE codes with respective threshold and accepting only those own-UE and other UE-codes that exceed their respective threshold to include in the detected code list; wherein some of the identified own-UE and other-UE candidate codes are removed from the candidate code list based on an energy measurement; and processing channels in the candidate channel list to thereby demultiplex and decode received data.
