Abstract
In this paper an unequal error protection scheme based on Rate-Compatible Punctured Convolutional codes employing Hierarchical PSK modulation is presented. New error bounds are derived and reported for AWGN and flat Rayleigh fading channels. Both soft and hard decision decoding techniques are considered in our analysis. The proposed scheme does not involve increased in complexity of resources and bandwidth expansion either. It is shown that by varying the signal to noise ratio and a specific constellation parameter set, which controls the level of error protection, significant error performance can be achieved over the uniform modulation case. All the established theoretical upper bounds are illustrated with numerical examples and these are also simulated using Matlab Simulink® 2017. Simulation results show that near-13-dB difference is achieved between the first and last priority sub-channels of the UEP communication system. The proposed scheme can find suitable applications in digital video broadcasting and Wireless JPEG2000 as well as H.265 data transmission systems.
