### Abstract

The paper considers the transmitter power dependences necessary to achieve the required error probability of the transmitted data on the utilization factors of the receiving antennas surfaces under conditions of coherent reception of millimeter-wave signals. Signals in the specified range of radio waves, due to a certain viscosity of the air and turbulent tropospheric vortices, are subject to lognormal amplitude fluctuations. In addition, the dependences of the probability of data transmission errors on the utilization factors of the receiving antenna surface for simple signals and signals protected by an error-correcting code in the considered communication channel were considered. The studies were performed by the analytical method in the MathCad computer simulation environment using the basic radio communication equation, taking into account lognormal amplitude fluctuations. The channel error probabilities were determined as mathematical expectations of signal error probability in Gaussian noise according to lognormal fading statistics. The calculation was performed for simple signals and signals encoded with a random error-correcting code. The results obtained make it possible on the one hand to determine the required transmitter power to achieve a certain error probability in the tropospheric channel, and on the other hand to evaluate the effectiveness of using a random error-correcting code in comparison with an uncoded signal to increase noise immunity and high data transfer rate in deep space scientific experiments.

AB - The paper considers the transmitter power dependences necessary to
achieve the required error probability of the transmitted data on the
utilization factors of the receiving antennas surfaces under
conditions of coherent reception of millimeter-wave signals. Signals
in the specified range of radio waves, due to a certain viscosity of
the air and turbulent tropospheric vortices, are subject to lognormal
amplitude fluctuations. In addition, the dependences of the
probability of data transmission errors on the utilization factors of
the receiving antenna surface for simple signals and signals
protected by an error-correcting code in the considered communication
channel were considered. The studies were performed by the
analytical method in the MathCad computer simulation environment
using the basic radio communication equation, taking into account
lognormal amplitude fluctuations. The channel error probabilities
were determined as mathematical expectations of signal error
probability in Gaussian noise according to lognormal fading
statistics. The calculation was performed for simple signals and
signals encoded with a random error-correcting code. The results
obtained make it possible on the one hand to determine the required
transmitter power to achieve a certain error probability in the
tropospheric channel, and on the other hand to evaluate the
effectiveness of using a random error-correcting code in comparison
with an uncoded signal to increase noise immunity and high data
transfer rate in deep space scientific experiments.
