MATLAB Modeling of DTMB Standard Transmission System

This document provides an in-depth exploration of MATLAB modeling for DTMB standard transmission systems. This comprehensive modeling approach incorporates multiple channel models and various modulation schemes, offering significant diversity and flexibility that makes it a powerful tool for various application scenarios. The implementation includes key MATLAB functions for signal generation, channel encoding, and modulation/demodulation processes. Users can configure parameters such as channel types (AWGN, multipath, etc.) and modulation methods (QPSK, 16QAM, etc.) through modular switching interfaces. The code structure employs object-oriented programming principles, allowing easy extension of new channel models or modulation schemes. Whether for academic research or commercial development, this modeling approach helps users better understand and apply the DTMB standard. The simulation includes error rate analysis, signal constellation diagrams, and performance evaluation metrics. We encourage thorough exploration of this modeling methodology and its practical application in your work.
