ABSTRACT:
A system and method for processing signals are disclosed. The method may include scrambling a first composite signal comprising N orthogonal sequences to generate a set of N channel signals. A second composite signal including M orthogonal sequences may be scrambled to generate a set of M channel signals. The M orthogonal sequences may be a subset of the N orthogonal sequences. The generated set of N channel signals and the generated set of M channel signals may be combined to generate K channel signals. K multiplexed channels may include the N channel signals and the M channel signals. The N channel signals may correspond to N antenna elements, and the M channel signals may correspond to M antenna elements. Each of the N channel signals may be spread utilizing a corresponding one of the N orthogonal sequences.
