Compressive sampling for DS TT&C signals based on sparsity analysis

Broadband is one of development trends of the TT&C system, which will inevitably lead to high speed sampling pressure and massive data problem. To aim at the issue, the compressive sampling for DS TT&C signals based on compressive sensing was studied preliminarily. On the basis of the in-depth sparse analysis for the DS TT&C signal, the phase-Doppler basic dictionary was built, and then simulation verification of the sparse representation and compressive sampling for the DS TT&C signal was carry out. The results of simulation show that compressive sampling for DS TT&C signals based on the built phase-Doppler basic dictionary is feasible which gets some noise reduction performance.
