Abstract

In this paper, a modified unequal power allocation scheme for the different bits of asymmetric turbo encoder has been investigated to enhance the performance. The simulation results and performance bound for the asymmetric turbo code with modified Unequal Power Allocation (UPA) scheme are obtained and compared with the system with typical UPA and without UPA. From the performance results, it is observed that the proposed asymmetric turbo code with modified UPA performs better than the system without UPA and with typical UPA and it provides a coding gain of 0.4---0.52 dB.
