VHDL MODELING OF PAYLOAD DATA STORAGE AND DATA PROCESSING BLOCK OF WI-FI MAC LAYER FOR TRANSMITTER

Aarti Sinha — 2016-12-10

For the wi-fi conversation, IEEE 802.eleven is one of the protocols to be had. The IEEE
802.11b uses the medium get right of entry to control layer (MAC) for wi-fi neighborhood
region community. these wi-fi neighborhood place networks use carrier sense more than one
get admission to with collision avoidance (CSMA/CS) for the MAC layer .however most
effective the MAC layer for transmitter is taken into consideration here for simulation. So, the
wireless transmitter module is divided into five blocks i.e. information Unit Interface block,
Controller block, Pay Load data storage, MAC Header register block and records
Processing block. in this paper we recollect only the simulation of MAC header sign in
blocks. So, other blocks i.e. facts unit interface block, Controller block, pay load records
garage block & information Processing block are not discussed similarly on this paper. A
subject programmable gate array (FPGA) device has been used because the hardware
implementation platform. The proposed MAC-layerhardware is carried out with Xilinx
xcv300e Virtex E FPGA.

Wideband filter using meta material at THz frequency

C.S. Mishra — 2016-09-12

Wideband filtering application using ceramic meta material is reported in this work.
Reflective properties of both SNG and DNG, glass and ceramic materials are presented.
Simulation results for both structures predict the wide reflected band is found at Terahertz
frequency pertaining to above structures. Also non linear variation of “width of the reflected
band” is found with varying the thickness of meta material structure.

Implementation of Sinusoidal Pulse-Width-Modulation (SPWM) for Photovoltaic (PV) and Wind grid applications.

Dr. Vijay Shrivastav — 2016-11-21

This paper offers with implementation of Sinusoidal Pulse-Width-Modulation (SPWM) for a
single-segment hybrid electricity filter generator for Photovoltaic (PV) and wind grid
programs. the use of policy iteration set of rules, an progressed variable step-size
perturbation and remark set of rules is contrived and it's far carried out proficiently the
usage of a hard-ware description language (VHDL) (Very excessive velocity included Circuit
hardware Description Language). the brand new generated grid source supplements the
prevailing grid electricity in rural homes for the duration of its cut off or constrained deliver
period. The software is used for generating SPWM modulation incorporated with a sunpower & wind energy grid device that's applied on the Spartan three FPGA. The proposed
set of rules plays as a conventional controller in phrases of tracking pace and mitigating
fluctuation output energy in regular nation operation which is shown inside the experimental
outcomes with a commercial PV array and HPW (peak Weight Proportional) show.
Simulation results display the validity with load of the proposed set of rules.

GPS* (GLOBAL POSITIONING SYSTEM) functionality : Review

Bhupendra Kumar — 2016-10-03

The Global Positioning System (GPS) is a U.S. space-based radio navigation framework that
gives dependable situating, route, and timing administrations to non military personnel
clients on a consistent overall premise - uninhibitedly accessible to all. GPS gives
uncommonly coded satellite flags that can be handled in a GPS beneficiary, empowering the
collector to register position, speed and time. Fundamentally GPS works by utilizing four
GPS satellite signs to figure positions in three measurements (and the time balance) in the
beneficiary clock. GPS gives exact area and time data for a boundless number of individuals
in all climate, day and night, anyplace in the world. Any individual who needs to monitor
where he or she is, to discover his or her way to a predefined area, or comprehend what
heading and how quick he or she is going can use the advantages of the worldwide situating
framework. Regular exercises, for example, managing an account, cellular telephone
operations, and even the control of force lattices, are encouraged by the precise planning
gave by GPS.

The Performance Of OSCM Transmission System

Prof. Anita k. S. — 2016-12-30

In this paper, the overall performance of OSCM transmission system using dual electrode MZ
modulator turned into analyzed and investigated by simulation thru using optimism software
program. The dual electrode z-reduce LiNbO3 MZM makes the usage of two linear
polarizer’s located before and after it respectively. by way of carefully deciding on the angles
of the 2 linear polarizer’s, the third order inter modulation and harmonic distortion may be
suppressed notably. The performance of the device changed into investigated by various few
parameters which include records fee, optical modulation index, subcarrier frequency,
section shift difference among branches of dual electrode MZ modulator, fiber length and
segment of the neighborhood oscillator at the receiver side.
