Compressive sensing in wireless mobile communication system at high data rate transmission

In this paper, the use of compressive sensing in a mobile communication system is proposed in order to increase the data rates. The objective is to increase the data rates of current and possibly future generation mobile systems. In the proposed system the speech signal is sampled below the Nyquist rate by using compressive sensing. The compressed spectrum is then transmitted over the wireless system and successfully reconstructed at the receiver without losing any significant information. In theproposed communication system, first the speech signal is modelled in such a way that theinput signal is sparse enough before applying compressive sensing. The sparse signal ismultiplied by the predefined measurement matrix. The output of the compressive sensingmodule is then transmitted to the receiver.
