摘　　要：伴随着无线电相关科技的不断发展进步,模拟信号无线电广播向着数字信号音频广播的趋势不断发展进步,与常规的音频广播相比较,数字信号无线电音频广播传播方案的特性更加明显,并且拥有更加光明的未来发展前景。不过目前来讲,数字信号无线电音频广播传播方案中依旧潜藏着许多相关弊端和问题,限制了该技术的推广。文章开始介绍了数字信号无线电音频广播传播方案现存的缺陷,然后给出了一定的行之有效的应对方案,在一定程度上弥补了数字信号无线电音频广播传播方案的漏洞和问题,提升数字信号无线电音频广播传播方案的延伸性和通用性,加速我国广播行业的进步。With the continuous development and progress of radio-related science and technology, analog signal radio broadcasting continues to develop and progress to the trend of digital signal audio broadcasting. Compared with conventional audio broadcasting,the characteristics of digital signal radio audio broadcasting transmission scheme is more obvious, and has a brighter future development prospects. However, at present, there are still many related drawbacks and problems hidden in the digital signal radio audio broadcasting transmission scheme, which limits the promotion of this technology. This paper first introduces the existing defects of the digital signal radio audio broadcasting transmission scheme, and then gives some effective countermeasures, which makes up for the loopholes and problems of the digital signal radio audio broadcasting transmission scheme to a certain extent, enhances the extensibility and versatility of the digital signal radio audio broadcasting transmission scheme, and accelerate the progress of China’s broadcasting industry.
