Technical Experience:

Academic Projects:

Analysis of adaptive echo cancellation using VSS LMS algorithm Tool: MATLAB

Eliminated the echo present in the data either generated internally or externally and produce an enhanced output using adaptive filtering technique.

Considered an input speech signal from AURORA database and performing multi rate processing to generate echoed version.

Used adaptive filters and least mean square algorithm to minimize the echo and reproduce the original signal.

Impedance Matching circuit at 3GHz Tool: ADS, Smith Chart

Designed single, pi, multi stub impedance matching networks and performing circuit, EM simulations on their microstrip versions and evaluating certain performance metrics.

Matched a complex 50-ohm load to 50-ohm using an open stub with center frequency 3.0 GHz.

Performed circuit & EM simulation and obtained a bandwidth of 7.6 %.

Various transmission lines and radial stubs were added to the design to improvise the circuit and achieve a bandwidth of 10.4 %.

Third order coupled line bandpass filter at 3GHz Tool: ADS, Smith Chart

Designed a third order microstrip coupled-line band-pass filter centered at 3 GHz and performing circuit, EM simulations. Overall Circuit is evaluated using (Figure of Merit) FOM.

The FOM value in circuit simulation was 3.385 dB and the FOM value in EM Simulation was 1.149 dB.

Disease detection in mushrooms using Image processing techniques Tool: MATLAB, Image processing

Obtained a database of diseased mushroom images from various sources.

Pre-processed these images using thresholding (manual & auto) technique.

Performed Histogram analysis, to extract diseased part of the mushroom.

Academic Papers:

M/M/1 Queuing model simulation

Evaluated a Queuing model with first come first serve basis and using a poison distribution process.

Sent a stream of random data to the system model and calculated data packet Arrival time and data leave time and Simulated its wait time in the queue.

Analysis of Wireless EM Nanonetworks in Terahertz band

Increased the channel capacity by overcoming several path and channel losses to increase the transmission rate between nanonetworks.

Evaluated Channel capacity by analyzing molecular absorption, path loss, noise temperature and system noise power.
