Beamforming in Millimeter Wave Systems: Prototyping and Measurement Results

Abstract

Demonstrating the feasibility of large antenna array beamforming is essential for realizing mmWave communication systems. This is due to the dependency of these systems on the large array beamforming gains to provide sufficient received signal power. In this paper, the design of a proof-ofconcept prototype that demonstrates these gains in practice is explained in detail. We develop a mmWave system with digitally controlled analog front-end. The developed prototype uses 60 GHz phased arrays and universal software radio peripheral (USRP) controllers. The software interface of our design is easily reproducible and can be leveraged for future mmWave prototypes and demonstrations.

A short survey on next generation 5G wireless networks

“…Creating and Controlling the Beam: we need a good understanding of mm-waves if we want to focus the energy to wanted direction. We can apply Beamforming in digital, analog or RF forms [17]. comparing digital and analog beamforming we can see that digital preforms better with and higher complexity and cost on the other side we see the analog as an effective and simple method but as not flexible as digital one [17].…”

Antenna training protocols: it is obvious that the directional antennas are the future of 5G networks and as far as it is good it also brings new problem with it is design, beams are either good aligned and have a connection or beams are not aligned at all and accordantly not connected.…”

Sistema 5G NR Indoor: uma Análise de Cobertura e Capacidade com MIMO

“…Na literatura existem trabalhos mais abrangentes, que visam implementar e testar funcionalidades do sistema. Trabalhos como [11] têm como objetivo comprovar as vantagens da conformação de feixe na propagação em mmWaves por meio de um protótipo em rádio definido por software implementado em USRP (Universal Software Radio Peripheral). Já em [12] é realizada uma análise comparativa entre algoritmos de conformação de feixe adaptativos, almejando melhorias em aplicações mMTC -vehicle-to-everything (V2X).…”

A USRP-Based Multi-Antenna Testbed for Reception of Multi-Site Cellular Signals

“…Similar work is presented in [11] where a real-time channel sounder for V2V propagation studies at 5.9 GHz is presented with the focus on spatial channel characterization. This article together with [12] are examples of testbeds where a switched array is used in conjunction with a single USRP board providing the Radio Frequency (RF) chain.…”
