Nafiz Ahmed Chisty, “Matrix Inversion Using QR Decomposition by Parabolic Synthesis”, Lund University (LTH), Master’s thesis book.

Abstract : Parabolic synthesis is one of the latest methodologies, proposed by Professor Peter Nilsson and Erik Hertz of EIT department at Lund University (LTH), for the implementation of unary functions in hardware. In the preceding research conducted at Lund University, it had been shown that parabolic synthesis is an effective solution, which is both fast and consumes less area compared to all the existing methods. The goal of this Master’s thesis is to develop hardware for the generation of three trigonometric functions (+sine, -sine and +cosine) using the novel approximation methodology, which is based on Parabolic synthesis, for the use in Givens rotations for implementing matrix inversion using QR decomposition. Two hardware designs has been developed, one for the parabolic synthesis and another for matrix inversion but due to time limitations the two hardware designs could not be integrated together. The paper mainly focuses on the implementation of the three trigonometric functions on both FPGA and ASIC and compares the result with metrics of speed and area and later a hardware solution for the overall system has been proposed.

Abstract : This paper presents a hardware design of an SVD based channel estimator. The details of the design are explained and some key aspects are discussed. The design has been implemented and tested on an FPGA and synthesized for an ASIC in 130 nm technology. It is shown that it is possible to get a clock frequency of 179 MHz for a 1.38 mm2 design. This corresponds to ~30 M estimates per second, which is more than needed in current wireless systems. Further, simulations show that this design would consume an average power of around 8.5 mW with a peak power at 14.2 mW. The presented data shows that it is possible to use these kind of advanced channel estimation strategies in wireless receivers, even though there has been no prior reports of these being implemented.

Abstract : Wireless Sensor Network (WSN) has touched our daily life and is getting developed day by day. Recently new WSN are designed to monitor environment or bio-organic purposes. Application of WSN technology cannot be limited within home appliances; it can also be used in Industrial application. Now a day’s Industries use expensive wired LAN network in order to monitor. In this paper a cost effective wireless Industrial appliances monitoring system has been designed and implemented. To collection data or monitor industrial machineries and equipment through web server the implemented system can be used and it also can take necessary actions based on the received data of temperature or humidity. The implemented system is cost effective and simpler than existing systems and utilizes Tree networking approach and uses NRF protocol in combination of router to upload data to the web server.

Abstract : Automatic Number Plate Localization and Recognition (ANPR) is a method that uses template matching on images to read the number plate of vehicles. This paper presents a robust method of license plate localization, segmentation and recognition of the character present in the located plate using an algorithm, which is based on pixel. The whole process has been designed in such a way that it can detect the conventional English number plate and can also detect Bengali alphanumeric number plate with adjoined Bengali letter by an easy and efficient algorithm which is robust to work and less time consuming. The ANPR systems are largely recommended for security system like traffic monitoring, electronic toll collection, and surveillance device and safety supervision. This whole system has been developed using MATLAB R2009a.

Design and Performance Analysis of Nano Microstrip Rectangular Patch Antenna at 0.25 THz

Abstract : To achieve the future demand of high data rates and high gain with better efficiency, two nano Microstrip patch antennas were designed with nickel and silver substrates. The operating or resonance frequency selected for the two antennas was 0.25 THz or 250 GHz. The main reason behind designing the antenna at 250 GHz is that the frequency range is completely free. The rectangular shape of the patch was selected because of the simplicity of dimension calculation. The transmission line model was taken for the analytical purpose. It is the simplest model of all other models. The values of patch width and length were calculated. The height of the antenna was taken too small for better performance. To operate the antennas at desired 250 GHz some dimensions were varied. Directivity of 16.37 dBi was found for the Nickel substrate patch antenna and 17.37 dBi directivity was found for the Silver substrate patch antenna.
