Abstract

In digital communication, the bandwidth efficiency is one of the most important parameter to measure different modulation schemes, while the separation of waveforms in time domain of existing modulation schemes make it difficult to improve their bandwidth efficiency. Hence, in past decade researchers and engineers continuously try to find out the way to solve out this biggest problem in the field of communication. Finally they were able to proposed such a scheme that is able to reconstruct the original signal in aliasing measurement, named as Compressive Sensing (CS). In this paper, we are using proposed scheme Compressive Modulation (CM) by combining Compressive Sensing (CS) with traditional OFDM in order to improve its bandwidth efficiency. Theoretical analysis and experimental results shows that bandwidth efficiency of OFDM is somewhat improved by using the proposed scheme (CS).
