Digital Beamforming Antenna : The Studies

Digital Beamforming Antenna studies are still relevant, here are some of good ones.

Digital Beamforming Antenna Array Overcomes Problems with Phased Arrays

A paper about a digital beamforming antenna array with polarisation multiplexing found that it outperforms phased arrays in terms of performance and RF circuit complexity. The combination of digital conversion, beamforming and polarisation ensures that all channels are handled in the analogue domain for efficient use.

Digital Beamforming Antenna : The Studies

Beamforming in LTE-A and 5G - How It Could Help You Get the Coverage You need

A study about beamforming in LTE-A and 5G showed that there is potential for beamforming to improve performance. Base stations equipped with an adaptive antenna array processor can adapt their beams to the user's location, providing better coverage for those in rural areas or areas with uncertain cell frequencies. These benefits can be particularly useful when using triple-rating theories, where each network is willing to share spectrum with a fourth network.

24GHz digital beamforming radar - an effective tool for object detection

An article about 24GHz digital beamforming radar with T-shaped antenna array was conducted in order to study the object detection performance. The results of this study showed that the 24GHz digital beamforming radar can be effectively used to detect objects. However, the use of an antenna array in this radar is somewhat disadvantageous as it deteriorates its performance when exposure to high signal levels. Therefore, it is recommended that the optimum antenna configuration for this Radar should be determined before it is put into use.

Examining the Use of Beamforming in Antennas to Increase Capacity

A study about digital beamforming has shown that the technique can be used to increase the channel capacity of antennae and also improve their signal to noise and interference ratios. This study used a different type of radiation pattern to test the technique.

Adaptive Beamforming for Joint State Estimation

A journal about an adaptive algorithm for digital beamforming of antennas is being performed. The algorithm is proposed to reduce the computational complexity and convergence time in joint state estimation problems. Based on estimated location information, the algorithm calculates the weights of smart systems and minimizes the error. This study provides valuable insights into optimizing antenna beamforming.

The Effect of Digital Beamforming on Received Signal Strength Indicator

A journal about the effects of digital beamforming using a smart antenna UKM was undertaken. This study used the L-probe fed inverted hybrid E-H (LIEH) arrays to get a better understanding of the performance. The LIEH arrays were used to study the effects of digital beamforming on received Signal Strength Indicator (RSAI). results showed that with a smart antenna UKM, the RSAI improved by about 20%. Overall, this study showed that with a smart antenna UKM, digital beamforming can improve signal quality.

A New Beamforming Design for Wireless Cellular Communication Systems

A paper about the use of millimeter wave frequency in future wireless cellular communication systems has motivated the development of large-scale antenna arrays. However, the conventional fully methods which require one radio frequency (RF) chain per element is not viable for large-scale deployments. To overcome this obstacle, a hybrid digital and analog beamforming design has been developed. This will allow for greater directional uniformity and improve overall performance.

Optical Modulation Strategies for Waveforms Generation

A review about many-antenna full-duplex with fully digital and hybrid functionalities was carried out. Results showed that this configuration offers several advantages over similar configurations using only a traditional digital amplifier/ junctionAncient waveforms were generated as well as ultimate performance measurements.
