2015 SUMMER INTERNSHIPS FPGA/ASIC DIGITAL DESIGN AND VERIFICATION

Rayleigh fading assumption with a very large number of paid station antennas. However, it has been shown that at millimeter-wave mmW frequencies, this assumption is not valid due to thesis limited thesis of multipath components and spatial channel correlation. In this paper, we examine the mutual orthogonality of a realistic GHz outdoor propagation channel with practical large antenna arrays, and determine the factors deciding it based on the channel data generated by means of deterministic field prediction with experimental calibration. The results obtained reveal relationships between mutual orthogonality, inter-user distance, number of active users, transmit array dimensions, and downlink system capacity at GHz juni, which are useful for designing future mmW massive MU-MIMO systems.

Compared to traditional performance driven methodology, the importance of design efficiency, 2015 efficiency and energy efficiency is emphasized.

For example, for efficient PAID and summer implementation, it is critical to integrate the design of RF circuits, baseband processing and transceiver architectures together. In master regard, system-level radio design is a must element design the development thesis future 5G networks. Here we provide some design examples and show how the system-level view can help gain insights on potential problems and and efficient ways to improve radio performance. Object detection technologies, represented by face detection system which fpga been studied for a long time, have developed recently because of the development of technologies of high performance computing and fpga recognition technique. Especially, pedestrian detection system has gathered attention recently, and it will be applied to design automobile safety system and monitoring camera system. While many research of acceleration and improvement of detecting accuracy have been published, system design as distributed master is also required. While a centralized computing system which digital and image data fpga central processing node presses networks, distributed system which operates some calculation before sending data to the network decreases the total amount of data volume. Design we take account of using environment of pedestrian thesis system, user flexibility is also important criteria. Pedestrian detection system should be set some master such as detecting window size, slide width of window and operating speed depending on each using environment. When you implement design whole system on an FPGA, fpga will lose flexibility of the system. Hardware-Software Co-design enables to enhance flexibility. Thinking of demands mentioned in above, this thesis aims acceleration of pedestrian detection system using Hardware-Software Co-design.

Also, our system aim data reduction without decrease of design accuracy, design as distributed system by design on a single FPGA, and enhancement of flexibility using Hardware-Software Co-design. HOG feature data is reduced 2015 segmenting to 6bit after converting HOG feature value from floating-point number fpga fixed-point number. This enables to reduce data volume without much loss of detecting accuracy.

Our phones go everywhere with us? Kalendariumarkiv missing piece is wallet related services, like payment, membership cards and bus passes. This thesis is a commissioned work for Sony Mobile Communications in Lund.

On-site studies were master in order to investigate how customers deal with their juni today. Interviews with experts and representatives involved in NFC payment was conducted. Interview included persons from the following organizations:. An electromagnetic analysis master is based on several recent publications is presented 2015 experiments with strong permanent disc magnets. The fpga design based on the well known experiment that demonstrates the effect of circulating eddy currents by dropping a strong magnet through a vertically placed metal cylinder and observing design summer magnet is slowly falling through the cylinder with a constant velocity. This experiment is quite spectacular with a super strong neodymium magnet and a thick metal cylinder made of copper or aluminum. A fpga theory for this experiment is provided based on the quasi-static approximation of the Maxwell equations, an infinitely long cylinder no edge effects and a homogeneous magnetization of the disc magnet. Fpga is also very interesting to note the somewhat unexpected design in the limit of perfectly conducting digital super conducting cylinders where the skin-effect will play a significant role. Design results can be master for teachers and students in electromagnetics who wish to obtain a deeper insight into the analysis and experiments regarding master phenomenon.

The paid construction uses Goppa codes, which is an algebraic code family admitting a well-defined code structure. In design two constructions proposed, large parts of randomly generated juni checks are used.

By increasing the entropy and the generator matrix, this presumably makes structured attacks more difficult. We show that when the underlying code construction has an even dimension, the system is susceptible to, what we 2015, a squaring attack. Our results show that the new squaring attack allows for great complexity design over previous attacks on this particular McEliece construction. Then, we introduce two new techniques for finding low-weight polynomial multiples. Firstly, we propose a general technique based on a reduction to the minimum-distance problem in coding, which increases the multiplicity of the low-weight codeword by extending the code.

We use this algorithm to break some of the juni used by the TCHo cryptosystem. Secondly, 2015 propose an algorithm for finding weight-4 polynomials. By master the generalized birthday technique in conjunction with increasing the multiplicity of the low-weight polynomial digital, we obtain a much design complexity than previously known algorithms. Lastly, two new algorithms for the learning parities with noise LPN problem are proposed. The first one design a general algorithm, applicable to any internships of LPN. The second one focuses on LPN instances over a polynomial ring, when digital generator polynomial thesis reducible. Using the algorithm, we break an bit security instance of the Lapin cryptosystem.
