01 FPGA Implementation of LTE-Advanced Downlink Physical Layer Transceiver
Sara M. Hassan, Abdelhalim Zekry

Abstract
To achieve a higher bit rates up to 1 Gbps for meeting the growing needs of the users of the mobile communication system the 3rd Generation Partnership Project (3GPP) introduced the Long Term Evolution Advanced (LTE-A) as an advanced standard for the mobile communication systems. The new features added by the LTE-A on the physical layer is a direct consequence for applying new modulation and coding techniques for both the Uplink and Downlink. The Orthogonal Frequency Division Multiple Access (OFDMA) was applied for the Downlink and the Single Carrier Frequency Division Multiple Access (SC-FDMA) was applied for the Uplink as well as turbo coding. This paper presents the design and implementation of the LTE-A downlink transmitter and receiver using a Field Programmable Gate Array (FPGA) according to release 10/11 on Virtex 6 XC6VLX240T FPGA kit using Xilinx® ISE® Design Suite version 13.3.All stages of the LTE-A downlink physical layer (PYH) transceiver, besides the time and frequency synchronization in a receiver,are implemented with 2×2 MIMO and Intra-band contiguous Carrier Aggregation type with two Component Carriers.

02 Fingerprint Authenticated Device Switcher Using Microcontroller and Arduino Uno
Sajan Rahman, Allen Dhakhwa

Abstract
Fingerprint matching has been successfully used by law enforcement for more than a century. The technology is now finding lot of other applications such as identity management and access control. In this context, an automated fingerprint recognition system and identification of key challenges are described along with the switching opportunities. The description is like a product design in this report implementing RTOS (Real time operating system) under the domain of embedded system. Fingerprint Recognition is a widely popular but complex pattern recognition Problem. In this paper, we have come with a novel approach to solve the existing problems with a proper Embedded System Design. In this project as well the fingerprint detection makes it coherent with the application involved within. The solutions viable are never ending but the switching mechanisms are to be sought after.

03 A Survey on Various Swarm Intelligent Techniques and Applications
Subhashis Mishra, Debashis Mishra, Dr. Madhabananda Das

Abstract
Swarm intelligence is an essential research field in today’s era which is being used in various applications such as image processing, signal processing, wireless sensor networks etc. swarm intelligence is mainly used to solve various optimization problems. It is the mutual comportment of decentralized and self-organized systems. Here system may refer to natural or artificial group. This paper has the main objective to do an extensive survey on various kind of swarm intelligent technique those are evolved since 1995 till date. It will also focus on various application of the swarm intelligence.

04 Arduino Based Real Time Instrumentation System for Remote Precision Farming
K. Mahesh Babu, R.Priyakanth, T. Hamsa Priya, K. Harini, M. Harshitha, S. M. Keerti Sree

Abstract
Precision agriculture is a farming management method based on observing, measuring and responding to inter and intra field variability in crops. Monitoring and recording of environmental conditions is necessary for precision farming. In this system, wireless sensors are used for monitoring soil parameters such as soil temperature, soil humidity, soil moisture and pH. This data is stored and analyzed based on which the decision about the suitable crop is made. This real time data is useful for efficient farming. A GSM module interfaced with Arduino is used for sending messages to a specific mobile device of a farmer with details about the suitable crop that can be grown in their respective fields. This method of soil testing in agriculture provides farmers with information about their crops. In this paper the estimation of different crop conditions are presented after a systematic study of relevant parameters involved in this estimation.

05 Analysis of TDM PON using Different Data Rates and Longer Reach
Sudhir Bussa, Riya Sachdeva, Ayushi Tripathi

Abstract
Telecommunication’s present need for reliable data transmission is more data rates with longer reach capability. These demands and requirements can be met by implementing optical networks. A passive optical network which reduces the amount of fiber and central office equipment required can give the desired improvements. This work analyzes and estimates the performance of TDM-PON Using Different Data Rates and Longer Reach by the use of 16 Users in the Optical Network Unit at the receiver’s side.

06 Smart Grid and Smart Meters – A Beginner’s Perspective
Padmaprabha V R, Jiju K, Divya D S

Abstract
Energy crisis is a global problem which has started decades ago, continues to affect the existing generations and those in the future. Increasing population, change in lifestyle, comfort and automation has increased much more than the past decades, thereby increasing the demand. The limited energy resources are insufficient to meet the demand thereby worsening the demand supply gap. Electricity is one of the most used forms of energy with a wide range of applications. Electricity Grid is the network of Generators, Transmitters, Distributors and Consumers of electrical energy. Modernization of Electricity grid by incorporating Smart and efficient methods have created a new generation of grids called Smart Grids. One attractive and important benefit of the Smart Grid compared to the conventional methods is the two-way communication facility connecting the utility and users. Monitoring of the energy consumed is done by Energy Meters which has undergone evolution through years from the basic Analog meters to the latest trend of Smart Meters. Besides providing the basic functionality of monitoring the energy usage, Smart Meter has several advantages. This paper studies the different aspects of Smart meter and Smart Grid from a beginner’s perspective.
