Abstract
A system and method for processing signals are disclosed. The method may include spreading N replicas of a received signal with N orthogonal sequences. A scrambled set of N channel signals may be generated based on the spread N replicas of the received signal. M replicas of a received signal may be spread with the N orthogonal sequences. A scrambled set of M channel signals may be generated based on the spread M replicas of the received signal. The generated scrambled set of N channel signals and said generated scrambled set of M channel signals may be multiplexed onto K multiplexed channel signals on a receiver chain, where M, N and K are integers. The spread N replicas of the received signal may be combined. The combined spread N replicas of the received signal may be scrambled.
