Compressive Frequency Sensing Techique Using Discrete Prolate Spheroidal Sequences

摘要

In this paper, we present a new frequency identification technique using the recent methodology of compressive sensing and discrete prolate spheroidal sequences with optimal energy concentration. Using the bandpass form of discrete prolate spheroidal sequences as basis matrix in compressive sensing, compressive frequency sensing algorithm is presented. Simulation results are given to present the effectiveness of the proposed technique for application to detection of carrier-frequency type signal and recognition of wideband signal in communication. Key words: compressive sensing, prolate spheroidal sequences, frequency identification.
