Abstract

This paper proposes two novel audio signal acquisition methods based on compressed sensing theory, which can perfectly achieve long time, continuous, high-speed acquisition of audio signal and real-time, reliable transmission of high-volume of sampling data in wireless sensor network with the limited resources. Reasonable experiments are designed to verify the effectiveness of the two algorithms,and the experiment results show that the two kinds of audio signal acquisition methods are reasonable, practicable and suitable for the wireless sensor networks.
