Patent ID: 6845104

Claim:
A method for communication in a time division multiplex system wherein access to a shared physical channel is assigned on a demand basis by allocating timeslots to provide multiple connections between transmitters and receivers, each given connection of the multiple connections having a given transmitter and receiver, the method comprising: at a given transmitter, allocating at least one time slot to carry forward link packet data on a forward link channel; dividing a given packet into at least one frame; encoding each of the at least one frames with a forward error correction code; further cover sequence encoding each of the at least one frames with a cover sequence unique to the given connection between the transmitter and the given receiver; combining cover sequence encoded frames from the given transmitter with at least one cover sequence encoded frame from another transmitter; and at the given receiver, performing a cover sequence decoding process by combining a received signal with a cover sequence unique to the given receiver of the given connection, to provide a candidate frame; and decoding the candidate frame using a forward error correction decoding process, the cover sequence encoding operable to be decoded only by the cover sequence unique to the given receiver corresponding to the given connection.
