Methods, apparatus and computer programs for obtaining data
First Claim
1. A method comprising:
- receiving a data signal from at least one sensor;
determining a quality of the received data signal, the determined quality being indicative of a sparsity of the received data signal in a sparse basis; and
providing, in response to the quality of the received data signal being within a first threshold, a first feedback signal to control a sampling basis of the sensor, wherein being within the first threshold corresponds to the received data signal not being sparse in the sparse basis.
