PROJECTS AND PAPERS

Design of Single Stage Low Noise Amplifier (Agilent ADS)

Designed Schematic circuit design and performed the stability analysis, two port gain analysis of LNA.

Analyzed the input and output stability of the amplifier and calculated S parameters.

Power Amplifier Design (Agilent ADS)

Designed and simulated a 1 GHz power Amplifier using Agilent ADS.

Performed Load analysis, designed input matching, output matching and combiner networks.

Reed – Solomon Encoder and Decoder.

An encoder at transmitter and decoder at receiver is designed and established a reliable error free connection.

Implemented Reeds-Solomon encoder and decoder which can correct up to 2 errors.

Two Stage Data compression method for Real-Time database.

The first stage is archive compression technique which is a lossy compression, and second stage involves loss less compression LZW technique. Archive compression technique is based on swinging door algorithm.

High speed, High capacity and good compression ratio is achieved and implemented.

Design of Medium length OFDM MODEM.

Implemented an OFDM Modem whose modulator is implemented by a 128-point o/p IFFT.

Demodulator uses some known spectral values to measure and correct the distortion caused by the channel.

Speech recognition based devices monitoring and control system.

Implemented a speech recognition module through which the user can control the devices based on commands using embedded c

The project aims in designing a system which is capable of switching ON/OFF the electrical devices based on the speech commands.
