Reconfigurable Physical Resource Block Using Novel – Beamforming Filter Circuit for LTE-Based Cell-Edge Terminals

Abstract

This article presents a novel reconfigurable physical resource block (PRB), where long-term evolution (LTE) and mobile cell-edge terminals are interfaced using low-power tunable second-order <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$G_{m}-C$ </tex-math></inline-formula> filter beamforming circuit, hence achieving an uplink–downlink (UL-DL) cellular system. A total of ten wireless multipoint (MP) terminals were structured and investigated. The BS-to-UAV-enabled terminals are propagated by line-of-sight (LoS) and nonline-of-sight (NLoS) beamforming. The subordinate terminals are handled using the derived Rayleigh signal distribution expressions. To guarantee higher frequency shift, the embedded control logic (CL) circuit is modeled upon the NMOS low dropout (LDO) regulator configurations with center frequency of 9.2 MHz and pass band of 1.4 MHz. The quality factors for both the first and second poles remain stable at 4.1 and 6.5 respectively. Stochastic analysis of the anticipated signal impacts with further estimation of its inherent variation challenges within the confined spectrum-sharing zone was corroborated. Our work is validated using an introduced direct and relay network density variations. The model’s performance evaluation compliments a ≥ 45.3-dB gain, an optimal transmission power and robust network sum rates in both LoS and NLoS conditions.
