Abstract

A High speed and reduced –area 2D discrete wavelet transform (2D-DWT) architecture is proposed. Previous DWT architecture is mostly based on the modified weighted lifting scheme. In order to achieve a critical path with only one multiplier. Experimental measurement of design performance in terms of area, speed and power for 90nm Complementary Metal Oxide Semiconductor (CMOS) implementation are presented, Results indicate that while BP design exhibit inherent speed advantages.DS design requires significantly fewer hardware resource with increased precision and DWT level.. In addition to the BP and DS design, a novel flexible DWT processor is presented, which supports run time and increase the performance of the DWT parameters .In this proposed approach were give an efficient hardware support to the VLSI architecture achieved by Weighted Lifted Wavelet Transform(WLWT).

Abstract

Phased Array RADAR has high processing gains but the area coverage is limited to a 120° cone whereas MIMO RADAR has a much enhanced flexibility for transmit beam pattern design. The proposed, is a technique for multiple input multiple output radar with co-located antenna which is called as  'Phased-MIMO radar‘. The new technique enjoys the advantages of the MIMO radar without sacrificing the main advantage of the phased-array radar which is the coherent processing gain at the transmitting side. The Phased-MIMO radar is limited to range independent diversity; this limits radar performance to mitigate non-desirable range dependent interference. The aspect of the proposed technique is to divide the FDA transmit array into multiple sub-arrays, each sub-arrays coherently transmits a distinct waveform with a small frequency increment. The beamforming performance as compared to phased-MIMO radar is tested by analyzing the ‗transmitted-received‘ beampattern and the output SINR performance. The possible future task is the application of phased-MIMO radar with frequency diversity in (RSN) radar sensor networks.

Abstract

This paper describes the development of POGIL based instructional design classes for complex engineering problems described in the Program Outcomes (PO) of National Board of Accreditation (NBA), India accreditation criteria. Embedded system Design course in Electronics and Communication Engineering course (ECE) is considered for experimentation. Subsequently it aims at providing students and interested fresh faculty an opportunity to design and build the project on their own. The aim of the project is to design a round robin based embedded system where the tasks are of their choice. To structure and complete their design part, both students and faculty were posed with a large number of questions. They were asked to refer literature and data sheets for their work. Once the design part was reviewed to avoid critical errors, students built their project and compared solutions to theoretical predictions. Feedback was collected and analysed to determine the effectiveness of POGIL in PO attainment. The reflections given by both faculty and students were positive, in particular students found that solving complex engineering problems are quite difficult and challenging compared to other prescribed book end exercises but POGIL helped them to be more constructive to build their knowledge.
