DIGITAL SIGNAL PROCESSING FOR RADIO MONITORING

Abstract

A radio monitoring system based on a receiver, interfaces and FFT analyzer is described. The controller of the system evaluates spectra and the frequencies and levels of sinusoid signals (carriers) are accurately measured by interpolation of spectral values. The interpolation procedure and a new interpolation algorithm is described. The Cramer-Rao Lower Bound is also calculated for real- and complex-valued input data. Real-life measurement results are also presented.
