Optimal power allocation for the proposed asymmetric turbo code for 3G systems

We proposed a new class of asymmetric turbo encoder for 3G systems that performs well in both “water fall” and “error floor” regions in Ramasamy et al. [Weight distribution analysis of proposed asymmetric turbo code for improved performance, Int J Electron Commun 60(7) 479–93]. In this paper, a mod...
