This paper presents the work completed thus far in the design of an optimal next generation WCDMA receiver structure for situations where data streams exhibiting small or large amounts of sparseness are received. The receiver will employ a measure of sparseness, allowing for almost real-time (per timeframe) sparseness estimation to be used in an optimal adaptive estimation technique. Simulation results presented indicates the need for sparseness estimation, as well as performance benchmarks of the standard receiver structure to be used as a reference for comparison.
