Abstract

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 P err ≥ 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 P err ≤ 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.
