A simulator for a decameter radio channel

G. G. Vertogradov

Abstract


The paper is devoted to analysis of experience in designing a computer-simulated imitator of a radio channel of decameter range of wavelengths, with regard to main physical mechanisms affecting the propagation of waves in the magnetoactive inhomogeneous nonstationary ionosphere. The signal processing is performed based on the fast Fourier transformation with partition of the processed sequence into individual frames. The simulator permits prediction of all traditionally used propagation characteristics of the decameter waves, including natural noise and station clutter.
