随着人们对广播需求量越来越大,建立在编码正交频分复用基础上的数字音频广播(DAB)因其具备高稳定性和优良的激光唱盘(CD)的特点得到广泛应用,而能带内同频道(IBOC)制式的数字音频广播能够播数字信号模拟信号,能够对目前的模拟接收机完全兼容并且成本比较低,实现了向全数字化DAB的平稳过渡。将对其进行详细阐述,希望对数字广播的应用带来帮助。
With the increasing demand for broadcasting, digital audio broadcasting (DAB) based on coded orthogonal frequency division multiplexing has been widely used due to its high stability and excellent compact disc (CD) Digital in-band (IBOC) systems, capable of broadcasting digital signal analog signals, are fully compatible with today’s analog receivers and at low cost, enabling a smooth transition to fully digital DAB. Will elaborate on it, hoping to help the application of digital broadcasting.
