Abstract
A method for processing signals includes generating at a receiver, a plurality of scrambled sets of channel signals based on a plurality of spread replicas of a received signal. The plurality of spread replicas may be spread using a corresponding plurality of orthogonal sequences. At least a portion of the generated plurality of scrambled sets may be multiplexed onto a corresponding plurality of multiplexed channel signals on a receiver chain of the receiver. The plurality of spread replicas of the received signal may be combined, and the combined plurality of spread replicas may be scrambled. At least one scrambling sequence may be overlayed on the combined plurality of spread replicas of the received signal. The generated plurality of scrambled sets of channel signals may be orthogonally multiplexed onto a corresponding plurality of multiplexed channels on the receiver chain.
