HF Channel Simulation

Abstract

The process of probing and measuring an HF channel for use in a stored channel simulator will prove useful only when the investigator has some knowledge of the channel conditions. Of particular interest are the channel Doppler characteristic and multipath structure. The operations required to provide a measure of these parameters include: (1) complex channel reconstruction; (2) prefiltering to improve delay resolution; (3) channel snapshot generation; and (4) Doppler estimation. A set of flexible Fortran programs which meet these specifications are described in detail. Software verification is achieved by means of a program generated single sideband HF test channel. In addition, programming changes to the previously reported channel measurement and reproduction software are documented. These result in significant decreases in computation time.
