Open AccessComputable performance guarantees for compressed sensing matrices
The null space condition for ℓ1 minimization in compressed sensing is a necessary and sufficient condition on the sensing matrices under which a sparse signal can be uniquely recovered from the observation data v...

Performance Analysis and Receiver Design for SDMA-Based Wireless Networks in Impulsive Noise
In this paper, performance analysis and receiver design in the uplink of SDMA-based wireless systems are performed in the presence of impulsive noise modeled as a symmetric alpha-stable process. The optimal re...
