Information protection in space communication systems using changes in radio wave propagation conditions

A technique is developed that allows one to estimate the increase in the probability of erroneous reception of information symbols in space communication systems up to Perr ≥ 10−2 due to carrier frequency lowering down to 70...60 MHz and changing conditions of radio wave propagation (mainly due to t...

Summary:A technique is developed that allows one to estimate the increase in the probability of erroneous reception of information symbols in space communication systems up to Perr ≥ 10−2 due to carrier frequency lowering down to 70...60 MHz and changing conditions of radio wave propagation (mainly due to the appearance of fading). The possibility is shown to provide for Perr ≤ 10−5 by applying, under these conditions, spatially separated reception on five antennas with a small correlation of fading (no more than 0.5) in processing branches.
