Brief Write up of Most Successful Research Projects:

Real-Time GPS Satellite Signal Simulator

A Real-Time GPS signal simulator (RTGPSSS) is an instrument capable of simulating high fidelity L1 C/A signal, which is fed at the RF front end of the GPS receiver. These signals are similar to the one exists at the antenna of the GPS receiver in real time. RTGPSSS test facilities are used to test the software and hardware of GPS receivers and their augmentation systems. Almost any type of GPS receiver test procedure requires the use of RTGPSSS. These simulators replicate transmitted RF signals from satellites visible at a receiver’s location. The simulators usually have a trajectory profile generator for dynamic receiver applications. In this project a low cost solution for the design of RTGPSSS using DSPs & FPGAs is considered.

Parallel Processing Solutions for Adaptive Digital Signal Processing

There is a great emphasis on using Adaptive Digital Signal Processing for a wide spectrum of applications in communications, signal and image processing. Engineers dealing with real-time, Adaptive Signal Processing are demanding computational speeds, normally not realisable using single Processors. Parallel processing has been proposed as a solution to computationally demanding problems. Most of the Adaptive DSP algorithms possess a high degree of parallelism. In any algorithm parallelism could be exploited at various levels, viz., Program level, Task level, and Intra Instruction level.
This project deals with the development of Parallel Adaptive DSP algorithms viz., Recursive Least Square (RLS), Least Mean Square (LMS), and Kalman algorithm for the real-time critical applications namely, Image Estimation and Multi Target tracking.

Design of Semantic Intrusion Detection Systems

Intrusion Detection is a very crucial aspect of network security. It is the technique used to detect intrusions in the network and alert the users. The project is developed as a semantic IDS engine working in the application level.
Given a set of rules (each dictating a number of constraints that the input data must fulfill to trigger it) the IDS engine will find malicious events using as few redundant comparisons as possible. A translator is developed which converts the simple user written rules to a format that could be understood by the Lex tool. BNF grammar for the simple user written rules is designed such that a semantically efficient rule-base is generated by the translator. The translator merges the newly generated rule-base with the already existing rule-base in the IDS. IDS implementation is done in Linux platform using Lex and Yacc tools. The system was implemented completely in web environment and the results are presented with performance analysis.

Store & Forward Payload

The primary payload of Polar orbit micro-satellite ANUSAT is Store & Forward (S&F) messages. S&F stores the messages in onboard memory and forwards them when the user requests them in the visibility period. This consists of development of both Data link layer and Application layer functionalities. HDLC protocol is used in logical link connection and polling technique is used for medium access control. The application layer functionalities are memory manager and scheduler. The target processor is Intel 80186. The executable code is triggered by a Tele command in the telecommand channel from the Master control station.

Image Processing Hardware

Developed a High Pass Filter (hardware) (Analog) to be used in Speckle Interferometry based experiments.
FPGA Based DSP System Development

Development of Developed IP Cores

Developed IP cores - FFT, Viterbi decoder

Microsatellite Project

A microsatellite (ANUSAT) is being developed at Anna University. The tasks assigned are detailed below:

Telecommand & Telemetry Station
A full fledged ground station has been implemented to carry out Telecommand transmission and Telemetry reception. The work involved integration of all the subsystems ranging from Antenna to data reception (transmission) on a PC. The complete Telemetry system has been already validated using HAMSAT signal.

Store & Forward ground station
A Store & Forward ground station operating at (VHF transmitter & UHF receiver) has been implemented. The system operates with BFSK modulation at 1.2kbps. The baseband receiver and transmitter sections have been implemented on an FPGA.

Content Based Image Retreival

It involves development of algorithms towards detection of an object in a video frame and classification based on the variations within the object class.
