Abstract

The paper is a detailed Monte Carlo simulation study of Bit Error Rate (BER) behaviour of the Binary Phase Shift Keying (BPSK) modulation across the Geostationary satellite communication links in the Earth Orbit. The paper examines performance characteristics of uplink and downlink based on extensive simulation taking into account of the realistic system parameters such as path loss, antenna gain, noise figure, and propagation delays. The simulation confirms theoretical performance of BER with real-world performance of link budget constraints in a standard GEO satellite at an altitude of 35,786 km. The findings indicate that there is a substantial variation in uplink and downlink Eb/N0 ratios (-43.25 dB and -179.55 dB respectively) among the differences in system parameters, and this result discerns the problems of design satellite communication links. The Monte Carlo method is useful in giving insights on end-to-end BER, and close results are presented with the theoretical performance BPSK curves in AWGN channels. This study will help address the knowledge gap in the area of satellite communication system design, optimization to achieve reliable data transmission, and clear mapping of the system parameters to end-to-end reliability in space-based networks of realistic space-to-ground constraints.
