Compression sensing theory enables a safe reconstruction of signals under certain conditions. Random measurement (sensing) matrix Φ is one of the necessary conditions which give a strong impact on the behavior of the method used to reconstruct the signal. A deterministic method is therefore proposed to construct a new matrix called Sinusoidal Sensi...

The Subspace Pursuit (SP) algorithm is one of greedy pursuit methods which is used to reconstruct of K-sparse signal. Unlike existing condition produced by Dai and Milenkovic in 2004 that suggests the residual value of current iteration is reduced from the previous iteration, our approach eliminates useless information by reducing the number of ite...

Compressed sensing (CS) is a new field used for signal acquisition and design of sensor that made a large drooping in the cost of acquiring sparse signals. In this paper, new algorithms are developed to improve the performance of the greedy algorithms. In this paper, a new greedy pursuit algorithm, SS-MSMP (Split Signal for Multiple Support of Matc...

A least support denoising-orthogonal matching pursuit (LSD-OMP) algorithm to reconstruct the sparse signal using less number of iterations from noisy measurements is presented. The algorithm achieves correct support recovery without requiring sparsity knowledge. An improved restricted isometry property-based condition is derived over the best-known...

This paper proposes a new fast matching pursuit technique named Partially Known Least Support Orthogonal Matching Pursuit (PKLS-OMP) which utilizes partially known support as a prior knowledge to reconstruct sparse signals from a limited number of its linear projections. The PKLS-OMP algorithm chooses optimum least part of the support at each itera...

We report a case of schistosomal orchitis simulating malignancy. The patient presented with a unilateral hydrocele, testicular enlargement and loss of testicular sensation. Orchiectomy was performed because of suspected malignancy. Tissue diagnosis was schistosomiasis. The incidence, pathogenesis and pathology of genital schistosomiasis are discuss...
