What is second-generation beamforming and digital beamforming?
Beamforming is an established technology for cellular communications and other applications (see the previous article on “What is beamforming?”). Beamforming was initially developed based on various analog signal chain techniques and processes. In general, beamforming combines antenna array elements to direct signals at controlled angles to maximize signal reception at specific receivers. Analog beamforming can […]
What is beamforming?
Beamforming is used in various applications, including sensor arrays, radar, biomedicine, WiFi, and wireless communications. It is an active approach that combines antenna array elements to direct signals at specific angles and create constructive interference. In contrast, other signals are subjected to destructive interference to maximize signal transmission and/or reception. Beamforming can improve the spatial […]
What is precoding and what are the benefits?
Precoding involves preprocessing of the transmit signal in an RF system. As described below, precoding uses channel state information at the transmitter to improve performance and increase spectral efficiency. It is used to implement the superposition of multiple beams, including several different data streams of information for spatial multiplexing. Precoding is the transmitter signal processing […]
Metamaterials for power and energy
The first two FAQs in this series considered the potential for metamaterials to have significant impacts on advanced optics, audio systems, thermal management, and various aspects of mmWave communications and radar. This final FAQ will consider the impact metamaterials are expected to have on energy harvesting (both solar electric and solar thermal) high-power long-distance power […]
