beamforming

The delay and sum beamforming is a time domain approach.

Beamforming uses directional antennas to focus a signal into a concentrated "beam."

Beamforming will also be used heavily in WiGig.

This is known as delay-and-sum beamforming.

Beamforming: A versatile approach to spatial filtering.

Precoding is multi-stream beamforming, in the narrowest definition.

Because there is no channel knowledge, there is no beamforming or array gain from diversity coding.

Subspace ML beamforming is obtained by eigen-decomposition of the sample covariance matrix.

Spatial precoding of intelligent antenna includes spatial beamforming and spatial coding.

"What Is Beamforming?"

When the receiver has multiple antennas, single-stream beamforming cannot simultaneously maximize the signal level at all of the receive antennas.

Enhance the signal-to-interference-plus-noise ratio (SINR) compared to that of a single sensor using conventional or adaptive beamforming.

To overcome signal decay, WiGig uses a process called adaptive beamforming (it's not the first or only system to do so, but is heavily reliant on it).

The phased array antenna has 24 elements; all are used for reception, while 16 are used for creating virtual receiver beams through digital beamforming.

Precoding includes spatial coding (SC) and spatial beamforming (SB)

As the beamforming weights are selected from the statistics, and not randomly, this approach outperforms random beamforming under strong spatial correlation.

Beamforming is spatial signal processing which makes spatial beam focused on the target direction and spatial beam nulled interference signal.

Beamforming is known as antenna array signal processing, where every antenna element is separated from its nearest element by half of the transmit signal wavelength.

The fidelity of underwater communication links can be greatly improved by the use of hydrophone arrays, which allow processing techniques such as adaptive beamforming and diversity combining.

In WiMAX, MRC at the Base Station is sometimes also referred to as Receive Beamforming.

Precoding includes spatial beamforming and spatial coding, where spatial beamforming improves the received signal quality at the decoding stage.

LOCATE - a suite of integrated products for spectrum monitoring, direction finding, adaptive beamforming and geolocation of HF signals.

A MIMO-related technique that can be used with WiMAX is called AAS or Beamforming.

Adaptive beamforming is used to detect and estimate the signal-of-interest at the output of a sensor array by means of optimal (e.g., least-squares) spatial filtering and interference rejection.
