Keywords: Digital alias-free signal processing Nonuniform sampling Spectral analysis and estimation Fourier transform a b s t r a c t A wideband multichannel spectrum sensing approach that utilizes nonuniform sampling and digital alias-free signal processing (DASP) to reliably sense the spectrum using sampling rates well below the ones used in classical DSP(More)
Current clinical diagnostics are based on biochemical, immunological, or microbiological methods. However, these methods are operator dependent, time-consuming, expensive, and require special skills, and are therefore, not suitable for point-of-care testing. Recent developments in gas-sensing technology and pattern recognition methods make electronic nose(More)
In this paper we propose to use digital fractional sample delayers to perform high precision beam steering at the baseband sampling frequency. The major advantages of the proposed technique are that the fractional sample delayer (FSD) used has a very flat magnitude response within the baseband width allowing greater than 20-bit resolution for a 35-tap(More)
