Abstract:This paper describes a method for interpolating power density spectrum measurements in order to find the center frequency and signal features of unknown radio signals. Signal features are retrieved by applying a non linear operation to the signal. The proposed interpolation method is more computational efficient than using large FFT sizes with zero padded data. The method can be used as part of the spectrum sensing function of cognitive radio handsets. The method was tested with both real-world captured signals and by simulation.
