摘　　要：文章主要探索中波广播发射过程中信道噪声的产生原因,分析信道噪声对广播发射过程所造成的影响。信道噪声会导致广播信号在传输过程中衰减,干扰广播信号的幅度和相位,使广播内容变得难以理解。针对这些问题,探讨一系列策略,包括采用高质量的发射和接收设备、采用噪声抑制技术、优化广播信号的频率和功率以及采用更先进的调制技术,旨在为实际工作中提升中波广播的传输效果提供参考。This paper mainly explores the causes of channel noise in the process of medium-wave broadcast transmission, and analyzes the influence of channel noise on the broadcast transmission process. Channel noise will lead to the attenuation of broadcast signals during transmission, interfere with the amplitude and phase of broadcast signals, and make the broadcast content difficult to understand. In view of these problems, a series of strategies are discussed, including adopting high-quality transmitting and receiving equipment, adopting noise suppression technology, optimizing the frequency and power of broadcast signals and adopting more advanced modulation technology, in order to provide reference for improving the transmission effect of medium wave broadcasting in practical work.
