Analysis of Inter-Satellite Terahertz Communication Link

Abstract

The domestic and foreign status of terahertz wireless communication is introduced, and the paper analyzes the feasibility of ultra high speed short range and high speed long range inter-satellite terahertz communication.The capacity of inter-satellite terahertz communication system under the ideal additive white Gaussian noise (AWGN) channel is studied.It simulates the inter-satellite terahertz communication link and calculates high gain antenna design parameter requirements by analyzing more than 100Gbps capacity of short range inter-satellite communication and more than 2.5Gbps capacity of long range inter-satellite communication.
