Computing one-bit compressive sensing via zero-norm regularized DC loss model and its surrogate
Kai Chen, Ling Liang, Shaohua Pan
One-bit compressed sensing is very popular in signal processing and communications due to its low storage costs and low hardware complexity, but it is a challenging task to recover…
