Abstract :
The work presented in this paper aims to establish whether a combination of the Logarithm of Likelihood Ratio (LLR), Turbo Codes and Modulation Schemes enhances high and efficient performance in communication systems by minimizing transmission error rates for any given bit combination. Performance Analysis and Interpolation of Turbo codes over Additive White Gaussian Noise and Rayleigh Fading Channels will be explored. This highly combinatorial technique should influence optimum performance in Broadband communication systems. Computed results are presented for various parameters employed in the formulations outlined throughout this paper.
