چکیده
AB-STRACT In this paper, we consider the signal-to-interference plus noise ratio (SINR) performance of several beamforming algorithms, taking particular account of the contribution of sources correlated with the desired signal. In addition, we derive an optimal method that maximizes SINR by combining with the desired signal estimate any components of the interference/multipaths that are correlated with it. To facilitate performance comparisons, we will only consider the case where the signal directions of arrival (DOAs) are precisely known. The extension t o unknown DOAs is straightforward. Our analysis includes the first order effects of array calibration errors, and is verified by numerical simulation.

Sequential homotopy-based computation of multiple solutions to nonlinear equations
IEEE Intl. Conf. Acoustics, Speech & Signal Processing (ICASSP) May 1995 Homotopy methods have achieved significant success in solving systems of nonlinear equations for which the number of solutions are known and the homotopy paths are bounded. We present a twostage homotopyprocess which does not require a-priori knowledge of the number of solutions to a system of nonlinear equations. This app...

Profound knowledge of the interaction between algorithms and digital signal processor (DSP) architectures is required to be able to efficiently design complex communications equipment. Whereas both algorithms and architecture find treatment in many courses individually, education focusing on design methodology for DSP implementation is found to be rare. This contribution describes a concept and...
متن کاملDIGITAL IMAGE HALFTONING BY NOISE THRESHOLDING - Acoustics, Speech, and Signal Processing, 1995. ICASSP-95., 1995 International Conference on
Approaches for digital halftoning of images using dithering threshold the input image with additive dithering noise. The paper presents a technique which thresholds the noise directly. The threshold is modified at each step such that the expected value of the output is equal to the input pixel’s gray value. Further, error feedback is used to correct the threshold. Tests on images show the metho...
متن کاملINCORPORATING MRI REGION INFORMATION INTO SPECT RECONSTRUCTION USING JOINT ESTIMATION - Acoustics, Speech, and Signal Processing, 1995. ICASSP-95., 1995 International Conference on
Single Photon Emission Computed Tomographic images(SPECT) have relatively poor resolution. In an attempt to improve SPECT image quality, many methods have been developed for including anatomic information, extracted from higher resolution, structurally correlated Magnetic Resonance images(MRI), into SPECT reconstruction process. These methods provide improved SPECT reconstruction accuracy if th...
متن کاملTREE STRUCTURED NON-LINEAR SIGNAL MODELING AND PREDICTION - Acoustics, Speech, and Signal Processing, 1995. ICASSP-95., 1995 International Conference on
We develop a non-parametric method of nonlinear prediction based on adaptive partitioning of the phase space associated with the process. The partitioning method is implemented with a recursive tree-structured vector quantization algorithm which successively refines the partition by binary splitting where the splitting threshold is determined by a penalized maximum entropy criterion. A complexi...
