Performance Analysis of Propagation in VHF Military Tactical Communication System

Abstract

The main challenge of military tactical communication systems is the accessibility of relevant information on the particular operating environment required for the determination of the waveform's ideal use. The existing propagation model focuses mainly on broadcasting and commercial wireless communication with a highs transceiver antenna that is not suitable for numerous military tactical communication systems. This paper presents a study of the path loss model related to radio propagation profile within the suburban in Kuala Lumpur. The experimental path loss modeling for VHF propagation was collected from various suburban settings for the 30-88 MHz frequency range. This experiment was highly affected by ecological factors and existing wave propagation effects such as reflection, diffraction, scattering, and Doppler effect. Radio propagation performance is evaluated by collecting received power at the allocated substation and comparing it against existing propagation models. The existing propagation model also will be tuned close to the measurement value by identifying the best path loss exponent to perform a suitable model for a suburban area. Theoretical assessments and analysis of the initial measurement stage for radio propagation show the extensive contribution of radio field from potential obstacles at lower VHF frequencies for both short and medium ranges around there. The explanation indicates the standard radio propagation prediction models that are generally reasonable for the suburban area. From the general error analysis, it is seen that, the performance of the LDPL with adjusting path loss exponent is the suitable model since it has least value of error metrics.

Enabling Technologies for Ultra-Low Latency and High-Reliability Communication in 6G Networks

“…This includes turning up mobile devices and test instruments in real-world settings and comparing the actual signal quality and strength with the values estimated by the simulation algorithms. These evaluations offer valuable information that can be used to improve network efficiency and modify coverage models [31][32][33][34][35][36][37][38][39][40][41].…”

Bandwidth Improvement of a Cone-Inverted Cylindrical and Cross Hybrids Dielectric Resonator Antennas

“…The main challenge of tactical communication systems is the accessibility of relevant information on the particular operating environment required to determine the waveform's ideal use. The propagation model focuses mainly on broadcasting and wireless communication with a high-directivity antenna [12]. It can be observed that the bandwidth percentage can be increased more than that of all the ultra-wideband hybrid DRAs listed in Table 1.…”
