• ### matlabCalculating incoherency in compressive sensing

· CS is based on a choice of a sensing basis Φ relative to a representation basis Ψ. There are many well known pair matrices for Φ and Ψ like random Gaussian and FFT and also they should have low coherency which can be calculated with μ ( Φ Ψ) = n ⋅ max 1 ≤ k j ≤ n φ k ψ j . Some of these Coherency values which are

Introduction. Compressed Sensing (CS) is a novel sensing/sampling paradigm that allows the recovery of sparse (few nonzeros) or compressible (quickly decaying entries) signals from far fewer measurments than the Nyquist rate. The sparsity assumption is easily realized in practice as for instance natural images are sparse in the Wavelet

This code demonstrates the compressive sensing using a sparse signal in Time domain. The signal consists of a UWB (Ultra Wide Band) pulse in time domain. The signal is sparse in Time domain and therefore K random measurements are taken in Frequency domain. After running the code the first figure shows the time domain signal and it s DFT.
