ACADEMIC PROJECTS

PPM-TH-UWB communication system design

PPM-TH-UWB physical layer simulation reference system for a short distance indoor impulse radio communication has been designed in MATLAB

This system uses IEEE 802.15.3a channel, PPM and BER is calculated using IRAKE, PRAKE and SRAKE schemes

System-level design for a mobile wireless user terminal

Designed a mobile wireless user terminal in MATLAB with QPSK modulation, convolutional encoding & Interleaving

This system uses General Packet Data Channel (GPDCH) which is subjected to Rician flat fading and Block phase estimation

Viterbi Decoding along with MRC,Deinterleaving, Puncturing has been used in receiver section and its performance is evaluated

Capture and analysis of data traffic using Wireshark

Data packets are captured in Wireshark during establishment and termination of TCP/IP session

Analyzed data by identifying various fields in DNS queries, Domain names, Video Streaming, Handshaking signals

Identifying how the packets are transmitted in command line using route hopping, transmission errors and corrections

Calculated Time-to-live of packet and loss percentage during connection and finding the Routing Path

Low frequency signal generator and scalar network analyzer

Designed hardware circuitry using DAC and Amplifier for generation of Analog signals and filtering and the circuit’s operation is tested for all the input parameters

Direct Digital Synthesis method is used to generate a sinusoidal/ rectangular/ triangular signal with ARM CORTEX M4 Processor on TI Board (TM4C123GH6PM)

SSI Protocol is used to communicate with DAC (MCP4821)used in our hardware circuitry

UART is used for the serial communication between the user and the controller

Subwoofer Amplifier Circuit

A Subwoofer Amplifier circuit is designed using TL072 low-noise JFET dual operational amplifier and two LM1875 power amplifiers.

All the components are connected, and the hardware circuitry is tested to operate with in all the input conditions and tested for stability.

Design of Real Time Operating Scheduler

A RTOS scheduling algorithm has been designed on ARM Cortex-M4F processor in Embedded C

This design uses preemptive and cooperative processes with the support of semaphores, interrupt handling, shell interface, priority inheritance, sleeping, yielding, priority scheduling.

Digital Image Processing and Digital Video Coding

Image Processing: Blurring, Zooming, Edge Detection, Interpolation, Color Space Transformation, Quantization

Image Filtering: LPF, HPF, BPF, Arithmetic, Geometric, Harmonic, Contra-Harmonic, Gaussian, Inverse and Wiener

Video Coding: Huffman, Golomb, LZ77, DPCM, JPEG-LS, JPEG -2000, JPEG BASELINE, CALIC, EZW, SPHIT

Reverse Image Search Engine

Background subtraction in Video Stream

Radiometric Alignment and Vignetting Calibration

Human face detection in color images & License Plate Detection in Video Stream
