摘要

广播电台是一个丰富但未被充分利用的多媒体内容来源。为了使用户能够获得这些信息,必须开发能够搜索无线电波段中包含的大量信息的新型导航器。本文介绍了在FPGA上实现的一种新的软件无线电广播媒体导航器的原型,它能够同时解调FM波段的所有频道并对它们执行音频索引,最终使用图形处理单元。

Software radio FM broadcast receiver for audio indexing applications
Broadcast radio is a rich but underexploited source of multimedia content. To make this available to users, it will be indispensable to develop new types of navigators capable of searching the large quantities of information contained in the radio bands. The article introduces a prototype of a new software radio enabled broadcast media navigator implemented on an FPGA, which is able to demodulate simultaneously all channel in the FM band and perform audio indexing upon them, ultimately using a Graphics Processing Unit.
