The increasing demand for high-quality digital broadcasting within modern architectural engineering and built environments necessitates transmission systems that deliver high efficiency, robustness, and reliability despite complex structural interference. This study investigates the enhancement of DVB-T2 transmission performance through Adaptive Coding and Modulation (ACM), focusing on its ability to optimize throughput and maintain signal integrity in dense urban and indoor architectural settings. DVB-T2’s baseline transmission efficiency of 30–50% higher spectral capacity compared to DVB-T is further improved using dynamic ACM techniques that adjust constellation order, code rate, and Guard Interval (GI) based on real-time channel conditions. Experimental simulations were conducted using 16-QAM, 64-QAM, and 256-QAM under Rayleigh and Rician fading typical of reinforced c.. Read More»
