【 摘 要 】

FOCal Underdetermined System Solver (FOCUSS) is a useful method through reweighted 2minimization for sparse recovery. In this paper, we introduce an improved FOCUSS by enhancing sparsity with two reweighted 2minimization. The reweighted FOCUSS method has higher mission success rate and better accuracy than FOCUSS. The simulation results illustrate the advantage of reweighted FOCUSS.
