Description: 数字音频广播(DAB)是继调幅(AM)、调频(FM)广播之后的第三代广播。与现行广播相比，DAB具有音质好(CD质量)、可实现多媒体及高速移动接收、可加密、发射功率小、覆盖面积大、频谱利用率高、抗干扰能力强等优点。DAB传送的业务可以是多种多样的，除了普通的音频节目，它也可以传送任何形式的其它数据，比如文字、静止图像或活动影音。因此，人们也称DAB为数字多媒体广播(DMB)。
本文主要介绍了基于PC和Cyclone II EP2C20F484C7的FPAG上实现DAB发射系统编码器的软硬件设计，设计充分考虑了电路规模和资源利用的要求。本设计最终用于测试DAB/DMB接收机。
