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

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 te ....etc

Grayscale Image Retrieval using DCT on Row mean,
Column mean and Combination



Abstract

Today in the age of information explosion, how to search appropriate data from huge information
pool has become vital issue. Images have giant share in this information pool. Because of easy
availability of imaging devices, millions of images are being added to image pool every day. Image
retrieval deals with searching relevant images from large image database. The paper presents novel
image retrieval techniques bas ....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

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

Jet impingement heat transfer – Part I: Mean and root-mean-square heat transfer and velocity distributions
Abstract
Impinging jets provide a means of achieving high heat transfer coefficients both locally and on an area averaged basis. The currentwork forms the first stage of a two part investigation of heat transfer distributions from a heated flat surface subject to an impinging airjet for Reynolds numbers from 10,000 to 30,000 and non-dimensional surface to jet exit spacing, H/D, from 0.5 to 8. In the present paper,the rel ....etc
