Summary There has been a lot of interest in the research community in recent years in Compressed Sensing for solving under-determined systems of equations or reconstruction of sparse signals from highly inadequate samples (in the original or in a transformed domain such as Fourier transform or Wavelet transform). To solve these problems, many techniques have been suggested and developed, a lot of which have focused on optimization. Among different optimization techniques l1 norm optimization has been source of much investigation. But later it was suggested that lp norm optimization with 0<p<1 can result in more accurate signal reconstruction. In this project a review of Compressed Sensing is offered and some approaches to signal reconstruction are discussed. In particular, methods involving lp norm optimization are evaluated. To this end, Matlab scripts have been developed to solve the lp norm optimization problem (0<p<1). They will be discussed in details and their results will be compared with results of l1 norm optimization.
