Motivation:                                   Multiple antennas in wireless systems offer a practical way to extend next generation communication capabilities which include higher data rate, reliability and high spectral efficiency. The increase in demand for higher data rates has led to the development of majorly two kinds of MIMO techniques Spatial Multiplexing and Space Time Block Coding (STBC).Spatial Multiplexing using V-BLAST systems are prone to high levels of inter-channel interference as all the antennas can transmit their data streams at the same instant. So, this technique needs complex decoders at the receiver antennas. On the other hand, Space–time block coding is a technique in which multiple transmitters transmit multiple copies of a data stream to exploit the various received versions of the data to improve the reliability of data transfer and reduce the decoding co...

Multihop Network Routing Using NS3 simulation and python #GROUP-7

by G Madhan, P Hemasai, K Manohar, A Rohith INTRODUCTION:                                          Communication is a major part in modern day life. I f we consider the network nodes, they are mobile in nature. It is not necessary that they have to stay at a particular position. And all these nodes are combined to make a multi hop network i.e. our present day networking system. The important task is to make sure that each communicating pair of nodes should be provided with the best available connection for data transferring. But here comes the problem as they are movable, their path will change time to time and should be updated regularly and this will definitely increase the complexity of the routing. We are going to simulate the routing process ...

GROUP 12 : PC to PC file transfer using LiFi Technology

This is an article written by, Bala Krishna Nair(S20180020201), J Krishna Chaitanya(S20180020214), K Samruth Kumar Reddy(S20180020217), U Yugander(S20180020256) under FCOMM project. Just imagine a situation where you are obsessed with your work in your PC in a work space with all the lights on and there is a light just above all the desks, as there is only a single WiFi router in the work space and as everyone in the work space are working, you and some others also facing the problem of poor signal, after struggling for sometime you feel like having a separate router only for you and that too right above your working desk, but you know that it is not possible, now I ask you how is the data coming from the WiFi router wireless to your PC? Basically WiFi uses waves in the radio frequency band of the electromagnetic spectrum between actual radio waves and microwaves. These electromagnetic waves carry the data, WiFi router is like an antenna that emits these ...
