Report-Milad-Vahedi.zip - In this project an adaptive beamforming technique is proposed based on directly minimizing the BER1. A particular approach that has shown real promise in achieving substantial capacity enhancements is the use of adaptive antenna arrays. A beamformer appropriately combines the signals received by the different elements of an antenna array to form a single output. Classically, this has been achieved by minimizing the mean square error (MSE) between the desired output and the actual array output. It is demonstrated that minimum BER (MBER) approach utilizes the antenna array elements more intelligently than the standard MMSE2 approach, since it directly optimizes the system’s BER performance rather than minimizing the MSE, where the latter strategy often turns out to be deficient.

beamforming-using-convex-optimization.rar - The goal of this thesis is to use convex optimization for a beamformer. By using convex optimization we observed the signal in desired direction and also reduced the error in the stopband regions for Least-square norm and Innity norm. The simulation results show that convex optimization is exible to be used for narrowband beamformer with minimum error in the stopband region.

Image-Watermarking-using-Tetrolet-Transform.rar - This paper proposes new watermarking technique based on Tetrolet domain. The Tetrolet transform is a new adaptive Haar-type wavelet transform based on tetrominoes. It avoids Gibbs oscillation because it applies the Haar function at the edge of the image. Our proposed watermarking algorithm embeds the watermark into the Tetrolet coefficients which are selected by considering different shapes of tetrominoes and uated the effectiveness of the watermarking approach by considering the quality metrics like RMSE, PSNR and Robustness parameters. The experimental results reveal that the proposed watermarking scheme is robust against common image processing attacks.
