摘　　要：基于软件无线电思想,提出了一个数字音频广播发射机的设计方案．在介绍系统基本概念的基础上,从MUSICAM信源编码开始,逐步介绍卷积编码、时间交织、DQPSK调制、频率交织和OFDM信号的形成,最终给出完整的软件流程和硬件设计方案,并对系统性能和可行性进行了分析．A design scheme for a digital audio broadcasting transmitter is provided based on the thought of software radio. Firstly, a MUSICAM and convoluotional coder is discussed, then time interleaving, DQPSK, frequency inter leaving and OFDM are all discussed step by step. Finally, a complete software realization and a hardware design are given. Brief analysis on the performance and reliability of the design is also provided.
