UWB receiver designs based on a gaussian-laplacian noise-plus-MAI model

Two novel receiver structures which surpass the performance of the conventional matched filter receiver are proposed for ultra-wide bandwidth multiple access communications. The proposed receiver structures are derived based on a more appropriate statistical model for the multiple access interference than the generally used Gaussian approximation. Reasons are provided for the slow convergence of a central limit theorem with regard to the multiple access interference, and the heavy tailed nature of the probability density function of the multiple access interference is also discussed.
