This project explores the development of a multiple input multiple output(MIMO)simulator using ray tracing techniques.This project gives an overview of ray tracing techniques, beamforming,MIMO channel models and MIMO systems.It explains the ability
In this course we will consider the following key themes Optimisation—and in general we restrict our attention to quadratic cost functions. Adaption—we consider a number of algorithms for iteratively converging to and tracking the optimum solution.
Ultra-wide-band (UWB) technology combined with multiple transmit and receive antennas (MIMO) is a viable way to achieve data rates of more than 1 Gb/s for wireless communications. UWB is typically applied to short-range and therefore mainly indoor c
The Automatic Dependence Surveillance-Broadcast (ADS-B) system is vulnerable to all kinds of interferences. Adaptive beamforming is widely used in array signal processing for enhancing a desired signal while suppressing interference and noise at the
A wideband-generalized pattern multiplication approach to evaluate the performance of an optical beamforming-based wideband antenna array is proposed and experimentally demonstrated, which enables the far-field measurement of a large wideband array w
Compared with state-of-the-art robust adaptive beamforming methods, therecently developed steering vector estimation-based beamformer and interference-plus-noisecovariance matrix reconstruction-based beamformer are known to provide better robustnessa
We propose and demonstrate a visible light communication (VLC) scheme based on space-division multiple access (SDMA) optical beamforming to accommodate multiple user devices in the VLC based on optical beamforming. SDMA optical beamforming is a techn
We propose and experimentally validate an optical true time delay beamforming scheme with straightforward integration into hybrid optical/millimeter (mm)-wave access networks. In the proposed approach, the most complex functions, including the beamfo
