Abstract

In view of current status of emergency relief in coal mine

an emergency voice communication system based on compressive sensing and WSNs is designed. According to sparse characteristic of voice signal

method of compressive sensing is adopted for voice signal random sampling and transmission. In receiving end of Sink

OMP algorithm and Co Sa MP algorithm are used for signal reconstruction respectively. The simulation experiment shows that Co Sa MP is better than OMP. Considering the transmission of wireless signal is limited

underground wireless communication experiment is conducted

it shows that in the cases of communication distance is 20 m; emergency voice communication in coalmine can be realized in real time and reliably.
