Next Generation Mobile Broadcasting BICM Module to Improve T2-Lite System Robustness

Abstract

Digital Video Broadcasting Next Generation Handheld (DVB-NGH) is the next-generation mobile TV broadcasting technology, which the DVB Project has developed. It’s the mobile extension of the high-performance Digital Video Broadcasting Terrestrial Second Generation (DVB-T2), with the most superior transmission technologies. One of the main modifications introduced by DVB-NGH is the advanced module of Bit-interleaved coded and modulation (BICM) based on a subset of DVB-T2 BICM elements. The diversity benefit gained by the modern features included in the DVB-NGH BICM module is examined in this study. This module incorporates two kinds of rotation schemes according to the specified coding rate: two-dimensional and four-dimensional rotated constellations (2D, 4D-RC). A comparison has been made between the acquired gain and the case of using the T2-Lite system’s fundamental BICM module, including the rotated constellations method. To confirm the efficiency of the created module, simulation results were done in MATLAB version R2020b using two fading channels: Rayleigh and 0 dB Echo. Finally, the acquired findings show a significant increase in system robustness when using the DVB-NGH BICM instead of the fundamental T2-Lite BICM module.
