System Capacity Analysis on Constellation of Interconnected HAP Networks

摘要

The high altitude platform (HAP) is an important communication platform for cloud storage in the next generation internet. The Multiple-input multiple-output (MIMO) techniques provide the significant diversity and multiplexing gain, which can improve the network performance effectively. In this paper, a virtual MIMO model is proposed by networking the constellation of interconnected HAPs. In a Rician fading, the diversity reception is investigated. The Probability density function (PDF) and cumulative distribution function (CDF) of the received signal-to-noise ratio (SNR) are derived. In addition, the CDFs of the system capacity and the system capacity with various SNR and Rician factors for different network configurations are analyzed. The simulation results validate the effectiveness of the performance analysis.
