Raspberry PI Based Global Industrial Process
Monitoring Through Wireless Communication

In this project, the parameters like voltage, current, temperature and the light intensity are measured and converting those parameters into digital by using the external ADC and displaying those on the LCD screen. any of the sensor goes beyond the threshold value, the buzzer will gives sound alert.

Android Based Smart Home System with Control via Bluetooth and Internet Connectivity

In this project we are controlling the electrical appliances from either Bluetooth or internet connectivity. for this we are using Bluetooth module and the in-built Wi-Fi module respectively. besides that the temperature and the gas sensors are used, whose status is sent to the Bluetooth app and web server as well. Any of the sensor goes beyond the set threshold value, then the alert will be given by alarm and alert message to both Bluetooth app and web server.

Vectored Implementation of Hierarchical 2^2n QAM

VLSI---IEEE TRANSACTION---2015

A complexity-reduced scalable vectored implementation for hierarchical 2^2n-QAM has been presented and proposed. The

hierarchical structure of modulation and demodulation algorithms

makes the proposed scheme suitable for hierarchical and adaptive QAM modulation.

Compressive Spectrum Sensing for MIMO-OFDM Based Cognitive Radio Networks

MATLAB--IEEE--2015 CONFERENCE PAPER

Cognitive Radio (CR) was proposed to enhance the utilization of the spectrum usage. Thus, the combination of MIMO-OFDM and Cognitive Radio, MIMO-OFDM based Cognitive Radio technology is treated as a prospect scheme for future dynamic spectrum access network or spectrum sharing system.

On the performance analysis of Partial Transmit
Sequence using Modified Flipping Algorithm for
PAPR Reduction in OFDM systems

                MATLAB ---2015----IEEE

A sub-optimal technique for PAPR reduction called modified iterative flipping (M-Flipping) algorithm has been proposed in this project, which offer better performance than other techniques like iterative flipping technique (I-PTS) and OFDM,
which we have discussed in this project

A Simulation Design of LTE Communication System under Adaptive Modulation Schemes

               MATLAB--2015---IEEE 

In this project the BER performance for QPSK, 16-QAM and 64-QAM are analyzed with turbo coding and without turbo coding. Turbo coding will give better performance when compared to uncoded system.

As extension, other higher order modulation schemes 256-QAM and 1024-QAM are considered.

When the modulation order is increasing the BER performance will degrade.

But always the coded system will perform better than uncoded system.

Performance of OFDM in time selective Multipath fading channel in 4G Systems

MATLAB--2015---IEEE CONFERENCE PAPER

In this project we are going to analyze the doppler effect on OFDM system

PSK modulation is considered in this project.

doppler is nothing but the frequency shift caused by the movement of trasnmitter or receiver.

To apply doppler shift on the signal we use  exp(j*2*pi*fd*(0:N-1)/N) 

fd is the Carrier frequency offset caused by doppler

formula for fd = v*fc/c

v is the speed

fc is carrier frequecny

c is speed of light
