It has been widely used in broadcasting and television transmission since the 2000s. DTMB provides efficient data compression, reliable transmission, and better image and sound quality to the users. Objective: The objective of this research is to study the perance of the DTMB transmission system. It involves analyzing and uating the transmission quality of DTMB, identifying the factors that influence the transmission quality, and proposing solutions to improve the transmission perance. ology: The research will be divided into three phases. In the first phase, a literature review will be conducted to understand the fundamental principles and technical specifications of the DTMB transmission system. In the second phase, the transmission quality will be assessed by investigating the Bit Error Rate (BER) and Signal-to-Noise Ratio (SNR) of DTMB. The third phase will focus on identifying the factors that affect the transmission quality by analyzing the channel characteristics, channel bandwidth, and transmission power. Moreover, different s will be proposed to improve the transmission perance such as advanced modulation, error correction coding, and interleaving. Expected Results: The results of this research will provide a comprehensive understanding of the DTMB transmission system s perance. It is expected that the research will contribute to identifying the critical factors that have a significant impact on the transmission quality. Additionally, it is expected that the research will lead to developing effective solutions to enhance the transmission perance of DTMB. Conclusion: DTMB is one of the most popular digital terrestrial TV standards in China. Understanding the perance of DTMB is crucial for improving the transmission quality of the system. This research will provide insights into the factors that affect the transmission quality of DTMB and propose effective solutions to improve the perance of the system. This study is significant for the broadcasting and television industry in China, as it can help improve their services and enhance the user experience.
