We proposed a new class of asymmetric turbo encoder for 3G systems that performs well in both “water fall” and “error floor” regions in [7]. In this paper, a modified (optimal) power allocation scheme for the different bits of new class of asymmetric turbo encoder has been investigated to enhance the performance. The simulation results and performance bound for proposed asymmetric turbo code wi...

There exist many bivariate parametric copulas to model data with different dependence features. We propose a new copula family that cannot only handle various patterns appear in the existing families, but also provides more enriched structure. The proposed construction exploits finite mixtures of normal distributions. mixing operation, distinct correlation and mean parameters at each mixture co...
