Abstract

The present subject matter provides a method for implementation in a wireless communication system that includes a plurality of base stations for providing wireless connectivity to at least a first mobile unit. A first signal processed using a first permutation mapping is communicated between the first mobile unit and a first base station. A second signal processed using the first permutation mapping is communicated between the first mobile unit and a second base station different than the first base station. The first and second signals are processed based on the first permutation mapping to extract data therefrom.
