Reconstruction of the Sparse Signal by using Approximate Message Passing Algorithm

Abstract

Reconstruction of the Sparse signal such as for audio signal,video signal, image signal is the major important role.We are going to recover the signal for the audio signal. The signal is recovered by using two algorithm such as AMP-M and AMP-T. These two algorithm coding are written in matlab and simulation from simulink will be used to get the specific outputs. AMP-M used as multiply accumulate unit for the recovery of unstructured matrices. AMP-T used as the fast linear transform. Hence recovery of the Sparse signal with the two algorithm is the main aim of the project .According to the research we have two technique to reconstruct the audio signal like compressive sensing, building of the FPGA hardware but in our project new technique is introduced to recover the audio signal by using two algorithms such as AMP-M and AMP-T .
