摘　　要：提出一种基于信道噪声技术的调频广播发射系统,旨在应对频谱资源紧缺和信号干扰问题。该系统通过在载波中引入人工噪声并结合信道均衡与纠错技术,显著改善广播音质并提升频谱利用率。实验结果表明,当噪声功率比为0.3时,系统在保证高信噪比的同时实现了最佳音质和最低误码率。A frequency modulationbroadcast transmission system based on channel noise technology is proposed to deal with the issues of scarce spectrum resources and signal interference.The system improves broadcast audio quality and enhances spectrum utilization by introducing artificial noise into the carrier and combining channel equalization with error correction technology.Experimental results show that when the noise power ratio is O.3,the system achieves optimal audio quality and the lowest bit error rate while ensuring a high signal-to-noise ratio.
