Abstract  Worldwide high bandwidth demand has created the need for exploring high frequencies spectrum for providing 5G broadband wireless communication. 5G broadband wireless communication is exploring millimeter wave (mmWave) frequencies spectrum for the frequencies band 28-GHz, 37-GHz and 39-GHz. In this paper, we discuss 5G mmWave communication and calculation of mmWave attenuation due to vegetation obstruction. Fitted ITU-R (F-ITU-R) model is used to calculate the vegetation obstruction attenuation for 28-GHz, 37-GHz and 39-GHz frequencies. This paper also presents transmission signal power control in 5G mmWave communication system using software defined radio (SDR) in the presence of vegetation attenuation. Further, 5G mmWave communication, Shannon channel capacity (SCC) is calculated for the frequencies 28-GHz, 37-GHz and 39-GHz in the vegetation environment. The results calculated in this paper are useful for the researchers as well as for the industries to calculate wireless system link budget analysis in the 5G mmWave communication system.

INTRODUCTION  Recently millimeter wave (mmWave) based communication system has been under attention worldwide under 5G based communication system [1-3]. Research is in progress to use mmWave based radio wave propagation to provide high speed large data bandwidth to the user across the world [4-5]. Millimeter wave (mmWave) frequency spectrum ranging from 3–300 GHz can support multigigabit data rates based on variable rates for a various corer users worldwide [6-7]. The Federal Communications Commission (FCC) has recently announced the 5G Millimeter Wave (mmWave) carrier frequencies bands 28-GHz band, 37-GHz band and 39-GHz band [8-11]. As we look for high frequency spectrum for high data rates; mmWave suffer with various wireless radio wave propagation losses due to various channel obstructions and impairments. Various mmWave channel obstruction sources are atmosphere, urban, vegetation and etc [2-3].

Millimeter Wave (mmWave) Attenuation Due to Vegetation When millimeter wave (mmWave) propagates through vegetation area it suffers with the signal attenuation [4]. This vegetation adds additional attenuation in the wireless channel while signal propagation in the same [16]. The vegetation area is random due to variable of the following [15]: Types of vegetation : tree or plant Size or Shape of the leaves, branches and tree trunks In-Leaf or Out-of-Leaf   The millimeter wave (mmWave) propagation will suffer following due to the vegetation [15]: • Multiple scattering • Diffraction • Delay and • Absorption of radiation.

Conclusion This paper presents the vegetation attenuation calculation and Shannon channel capacity calculation in the presence of the vegetation area for the 5G millimeter wave (mmWave) communication system. The mmWave vegetation attenuation and Shannon channel capacity is calculated for the frequencies 28-GHz, 28-GHz & 39-GHz. The objective of this paper is to study the effect of the vegetation attenuation on the calculation of Shannon channel capacity by using SDR based 5G millimeter wave (mmWave) communication system. It is visible through graphs that as depth of the vegetation increases, the SCC decreases. It is shown thorough simulation results that the from the results that the SDR based 5G millimeter wave (mmWave) communication system channels at the frequencies 28-GHz, 28-GHz & 39-GHz undergoes through signal attenuation due to vegetation effect. The channel capacity of the SDR based 5G millimeter wave (mmWave) communication system can be increased well in advance as per the demand and need of the channel and receiver. Adaptive signal power transmission control for SDR based 5G millimeter wave (mmWave) communication system can be provided to have efficient and optimum power transmission.
