摘要

尽管应用了高度复杂的信道编码技术[3]，但在几种接收条件下仍会发生不可纠正的错误。在城市或山区或覆盖区域的边缘，传统的调频接收机在移动接收时存在可听失真。DAB可以在不可纠正错误的情况下提供智能隐藏技术。已知有不同的方法可以隐藏持续时间长达约20ms甚至超过1ms的突发误差[4]。

Source related error concealment techniques for Digital Audio Broadcasting (DAB) considering the listeners perception

In spite of applied high sophisticated channel coding techniques [3] non correctable errors wiU occur during several conditions of reception. Conventional FM-receivers are well known for audible distortions during mobile reception in urban or montaineous regions or at the fringe of the coverage area. DAB could provide intelligent concealment techniques in the case of non correctable errors. Different methods are known to conceal burst-errors of durations up to some 20ms or even more than l a m s [4].
