浅述基于压缩感知的语音流媒体信号的丢包恢复

Packet Loss Recovery of Speech Streaming Signals Based on Compressed Sensing

本研究的目的是为了引入一种基于压缩采样技术的新方案,用于重构多媒体流中丢失的数据。通过使用交织技术将语音流媒体信号封装在发送方的不同分组中。压缩采样技术用于在接收端丢失数据包的情况下恢复音频信息。本文为语音音频信号提供实验结果,说明提出的方法具有可行性。

The aim of this study is to introduce a new scheme,based on a compressive sampling technique,for the reconstruction of lost data in multimedia streaming. The audio streaming data are encapsulated indifferent packets,at the sender,by using an interleaving technique. The compressive sampling technique is used to recover audio information in case of lost packets,at the receiver. Experimental results are presented for speech and musical audio signals which illustrate the performances and the capabilities of the proposed methodology.
