WORK EXPERIENCE

Azad University branch Jolfa, Ahar and Ilkhich Tabriz Sep2013- Jun2016

Lecturer

Digital Logic Design Signals and Systems Digital communication MATLAB Programming Microprocessors FPGA Lab

Projects

Automatic number plate recognition with MATLAB

Used image digital processing technique like threshold logic, morphology process, edge detection concept to choose the candidate place for plate and used geometrical criteria like area, length to width scale to detect the plate place and also matching criterion was used to plate digit recognition in main algorithm

Steganography in Images and Audio file with C++

Used image with JPEG2000 format and audio with wav format files as a cover file, secret message was put in wavelet coefficients’ LSB with threshold amount and shared key. algorithm had least impact on original file quality

Implement SPI protocol on FPGA

Full duplex connection, data port is defined as a generic to have a definable data width. It allow communication with user specified number of slaves, which may require independent SPI modes, data widths, and serial clock speeds. algorithm was implemented on Spartan 3

Designed servo motor Controller with Wi-Fi module on FPGA This project was designed based on Micro Blaze, used CC3000 as a Wi-Fi module and VHDL code implemented on Spartan 6

Simulated OFDM technique in LTE with MATLAB

Used 2048- FFT and orthogonal frequency technique on digital signal, consequently it transferred by AWGN channel, on the receiver side used IFFT to achieve original signal and also cyclic prefix considered in this simulation. Technical oral presentation and written report is given as coursework technical talk Birjand Uni. Nov 2010

Route Tracking and error estimation with Kalman filter Used a Kalman filter to estimate the position of a ball (object) moving in a two- dimensional space as an offline mode. It estimated the present position by updating the Kalman state vector, which includes the position, velocity, and acceleration of the moving ball (object).

final results and the design was presented as a coursework final project Birjand Uni. Aug 2010

Simulated AWGN channel BER (Bit Error Rate)

QPSK and CPM modulation techniques were Used for Digital communication and wireless communication BER for AWGN channel was simulated in MATLAB. Birjand Uni. May 2010

Implementation of LMS Adaptive Filter on FPGA

Transfer function is self-adjusted according to the LMS, algorithm driven by the error signal and it was implemented on Xilinx Spartan3 Birjand Uni. Mar 2010
