Abstract:
1. A method for multiplexing K channels on to a receiver chain, the K channels including N channels corresponding to N antenna elements and M channels corresponding to M antenna elements, the method comprising: spreading each of the N channels according to a corresponding one of N orthogonal sequences so as to form N spread channels; overlaying a first scrambling sequence onto the N spread channels so as to form a first set of N channels; spreading each of the M channels according to one of the N orthogonal sequences so as to form M spread channels; overlaying a second scrambling sequence on to the M spread channels so as to form a second set of M channels; combining the first set of N channels and the second set of M channels so as to form K multiplexed channels; and providing the K multiplexed channels to the receiver chain.
