One of the main design challenges in wireless sensor networks (WSNs) is craggy range sauvignon blanc 2022 achieving a high-data-rate transmission for individual sensor devices.The high altitude platform (HAP) is an important communication relay platform for WSNs and next-generation wireless networks.Multiple-input multiple-output (MIMO) techniques provide the diversity and multiplexing gain, which can improve the network performance effectively.

In this paper, a virtual MIMO (V-MIMO) model is proposed by networking multiple HAPs with the concept of multiple assets in view (MAV).In a shadowed Rician fading channel, the diversity performance 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 average symbol error rate (ASER) with BPSK and QPSK is given for the V-MIMO model.The system capacity is studied for both perfect channel state information (CSI) and unknown CSI individually.The ergodic capacity with various SNR and Rician factors taylor te400 for different network configurations is also analyzed.

The simulation results validate the effectiveness of the performance analysis.It is shown that the performance of the HAPs network in WSNs can be significantly improved by utilizing the MAV to achieve overlapping coverage, with the help of the V-MIMO techniques.
