Abstract

Equal-gain combining (EGC) is a conventional linear combining scheme used in non-coherent energy detection receiver for ultra-wideband (UWB) signals. However, due to the nonlinear nature of decision boundary, the EGC results in a suboptimal test statistic. In this paper, we propose a new design for a nonlinear combining energy detector based on Gaussian approximation, in which the energy detection problem becomes a general Gaussian signal detection problem with unequal-mean and unequal-variance. Numerical results indicate that the proposed detector exhibits better performance than the conventional energy detector.
