Abstract

DVB-T2 offers the best levels of efficiency, reliability, and flexibility of any digital terrestrial broadcast technology now available. It provides the most up-to-date coding and modulation techniques to make the valuable terrestrial spectrum extremely effectively usable for many types of transmission. The mobile configuration of DVBT2 also known as T2-Lite, employs a constrained set of possible modes that are suited for movable transmission and reduce the demands placed on the receiver. This study compares the T2-Lite system's performance before and after using constellation rotation and cyclic Quadrature (Q) delay methods among different types of constellations, coding rates, and fading channels. Results show a significant improvement in T2-Lite system performance while using a rotating constellation in a bad fading environment. Moreover, the utilization of this technique enhances DVB-T2 Lite gain. All simulation of system components and channels were carried out in MATLAB R2021a software.
