Holographic Beam Forming and MIMO

چکیده
Every cellular generation has offered new bands, lower latency, and faster data rates. What really defines wireless generations are the major technology shifts that set them apart. The transition from analog to digital communications marks the boundary between 1G and 2G. 3G introduced CDMA techniques for significant spectral efficiency gains. 4G LTE is nearly at the theoretical limits of wireless resource utilization, leaving little room for significant network improvement where frequency and time are the only free dimensions (Figure 1).

متن کاملMeasuring the deposited energy from a non-ionizing laser beam in water by digital holographic interferometry
Digital Holographic interferometry is a powerful and widely used optical technique for accurate measurement of variations in physical quantities such as density, refractive index, and etc. In this study, an experimental digital holographic interferometry setup was designed and used to measure the amount of energy changes induced by absorption of radiation from a non-ionizing infrared laser beam...
متن کاملMassive MIMO Beam-forming for High Speed Train Communication: Directivity vs Beamwidth
High-mobility adaption and massive Multiple-input Multiple-output (MIMO) application are two primary evolving objectives for the next generation high speed train communication system. In this paper, we consider how to design a location-aware beam-forming for the massive MIMO system. We first analyze the tradeoff between beam directivity and beamwidth, based on which we present the sensitivity a...
