Adaptive Algorithms for Filtering Ionograms and Measuring Channel Parameters to Estimate its Availability

摘要

Paper is addressed to the problem of increasing efficiency of data transmission across a HF radio channel. The algorithms for estimating the parameters of each radio channel from the useful frequency band by processing recorded ionograms were developed. Additionally, we developed the algorithms for estimating HF radio channel availability with the use of the sounding data to support digital HF communication systems.
