This thesis begins with a brief study of several multiuser detection techniques followed by an investigation of subtractive interference cancellation techniques two basic schemes, successive interference cancellation (sic) and parallel interference cancellation (pic) are discussed in detail and other schemes based on these two, a hybrid and a. Improved multiuser detection in code-division multiple access communications jie luo, phd university of connecticut, 2002 in code division multiple access (cdma) communications. Multiuser detection in multiple input multiple florida international university miami, florida multiuser detection in multple input multple output i dedicate this thesis to my wife, who takes care of my life, loves my family and me, and supports my research. A multiuser detector fulfilling these conditions would be an ideal candidate for practical implementation such a detector can in fact be devised by rewriting the system for transmission and reception in a cdma system, it becomes clear that we are dealing with a simple equalization problem rather than a complex detection problem. The scientific world journal is a peer-reviewed, open access journal that publishes original research, reviews, and clinical studies covering a wide range of subjects in science, technology, and medicine.

Consequently, to study the convergence behavior of the gsic detector, we propose two new corollaries that extend the famous work of kahan (varga, matrix iterative analysis, 2000) to the case where the relaxation factor is a matrix instead of a scalar. This paper presents several multiuser detector algorithms: the conventional detector, the linear mmse detector and the linear adaptive mmse one. The thesis deals with the application of subspace-based techniques to blind channel estimation and multiuser detection for multi-rate ds/cdma, including single-carrier and multicarrier scenarios.

In chapter 2, the necessity of introducing multiuser detection in cdma systems is expounded, and the principles of multiuser detection and the optimal multiuser detector are presented then, several commonly used linear and nonlinear suboptimal multiuser detectors are described, and their advantages and disadvantages are pointed out respectively. Dedication this thesis and work in multiuser detection is dedicated to my lord and saviour, our lord jesus christ fear of the lord is the beginning of knowledge. This research investigates the use of adaptive receivers for multi-user detection to overcome some of the deficiencies of a conventional receiver and, hence, suppress the multiple access interference (mai) and narrow band interference (nbi) in ds/cdma wireless systems. Adsl system enhancement with multiuser detection a thesis presented to the faculty of the division of graduate studies by liang c chu in partial fulfillment of the requirements for the degree of.

Multiuser detection and interference rejection claes tidestav keywords: decision feedback equalizer, multiuser detection, interference rejec-tion, antenna arrays, ds-cdma,near-far resistance in this thesis, we will almost exclusively use linear, discrete-timefilter and channel descriptions a scalar and causal, discrete-timefilter can. Quantum signal processing (qsp) as formulated in this thesis, borrows from the formalism and principles of quantum mechanics and some of its interesting axioms and constraints, leading to a novel paradigm for signal processing with applications in areas ranging from frame theory, quantization and sampling methods to detection, parameter estimation, covariance shaping and multiuser wireless. The presentation focuses on the study of cooperative multi-antenna techniques in multibeam satellite communications in a multibeam satellite context, multi-user detection and precoding techniques are examined for the next generation of broadband satellite networks. This thesis contains two main parts: the first part investigates the decoding of convolutional codes using a recurrent neural network and a support vector machine on a classical single-user communication system, and the second part studies a multi-user detector for a cdma system based on a support vector machine.

Practice simulation for multi-user detection algorithm, the traditional method is static simulation using matlab, although it is a good reflection of the simulation results of the multi-user detection algorithm, but it can not reflect its process, and the program design is also more cumbersome, not enough intuitive, not with a certain degree of. The proposed multiuser detector is compared to other multiuser detectors in terms of ber and complexity simulation results illustrate the superiority of the proposed scheme compared to actual. Fortunately, multiuser detection is a scheme that can effectively counteract this multiple access interference however, the optimum multiuser detection scheme is far too computationally intensive for practical use.
