Partial-norm-constrained sparse recovery algorithm and its application on single carrier underwater-acoustic-data telemetry
To solve the problem of single carrier underwater-acoustic-data telemetry,compressive sensing (CS) provides competitive performance of compression and recovery with low energy consumption.The primary objective of CS is to minimize the l<sub>0</sub>norm,which is an NP hard problem.Hence,t...

| description | To solve the problem of single carrier underwater-acoustic-data telemetry,compressive sensing (CS) provides competitive performance of compression and recovery with low energy consumption.The primary objective of CS is to minimize the l<sub>0</sub>norm,which is an NP hard problem.Hence,the common methods were transferred to minimize l<sub>1</sub>norm.However,l<sub>1</sub>norm minimization provided a limited accuracy.A partial-norm-constraint (PNC) based sparse signal recovery method was derived,which adopted PNC as a zero attraction in a Lagrange method,to distribute the soft threshold for the non-zero taps.The proposed method is used for at-sea data telemetry.Combining with DCT,the proposed method improves the recovery accuracy. |
