Abstract:
The combination of antenna array beamforming with multiuser detection can effectively
improve the detection efficiency for wireless communications under multipath interference,
especially for the applications in a fast fading channel. The authors study the performance of an
adaptive beamformer incorporated with a B-MMSE detector, which works on a unique signal
frame characterised by training sequence preamble and data blocks segmented by zero-bits. Both
the beamformer weight updating and B-MMSE detection are carried out ....etc

Abstract

The rapidly increasing demand for PCS has provided the impetus to design adaptive antenna arrays to improve spectral efficiency and enhance system capacity. With increasing data rate in some PCS application like DECT( Digital European Cordless Telecommunications), higher BER would degrade the system performance further. An adaptive antenna array testbed using 12 elements was built to evaluate its performance on high data rate mobile communications in an indoor environment for DECT applications. The simultaneous data sampling rate ....etc

lms algorithm adaptive beamforming matlab code

Abstract

Array processing involves manipulation of signals induced on various antenna elements. Its capabilities of steering nulls to reduce co channel interferences and pointing independent beams toward various mobiles, as well as its ability to provide estimates of directions of radiating sources, make it attractive to a mobile communications system designer. This paper presents 8-elements array with inter-element spacing /2 an optimum value to avoid grating lobes. An Adaptive beamforming is a ....etc

Adaptive beamforming plays an important role in sensor array systems in countering interference outside of the direction of interest. However, calculation of the adaptive weights generally requires a large number of operations that rapidly grows with the number of antennas. Consequently, a large number of programmable processors is commonly required to calculate the weights, which in some systems may present excessive weight, volume and power requirements.Field programmable gate arrays (FPGAs) offer a credible alternative to re-programmable tec ....etc

Analogue Beam Forming

Analogue Beam Forming (ABF) means, that the received echo signals from each element of the phased array antenna, are combined at the RF carrier frequency level. This analogue beam former feeds up to four centralized receiver channels, down-converting the signal to the basic band (or to an intermediate frequency, IF). The following Analogue-to-Digital Converter (ADC) digitizes the IF or the video signals.
Digital Beam Forming

Digital beam forming (DBF) can be realized at element level or at sub array level. In DBF-archite ....etc

Hello, I have to do the design of digital beamforming for transmitter. When transmitting, a beamformer controls the phase and relative amplitude of the signal at each transmitter, in order to create a pattern of constructive and destructive interference in the wavefront. Do you have any ideas on the matlab coding? ....etc
