I always try to work on a reasonable price and to give the best out of me. I assure that I can give you a high quality work. I always like to build good relationship with whom I work so that everybody gets satisfied. Masters Communication and Signal Processing, Newcastle University, UK. Schematic and PCB design Tools: Altium Schematic entry tool, Cadence Orcad Simulation Tools: Orcad Pspice, LTSpice, Tina TI,MaTlab Memory interfaces: SDRAM, DDR/DDR-II, NAND Flash, NOR Flash, EEPROM, uSD Card Peripheral interfaces: Texas Instruments,10/100 Mbps Ethernet, RS-232 interface, RS485 interface, USB interface, UART, Sensors, audio and video interfaces,LCD Standards: I2C, I2S, SPI, MII, RMII, USB Interface, SD Card, Power Management and Power Sequencing, SIM Safety Design: EMC Standards, Designing the Board with Safety Standard ( IEC 61000-4-5) etc. PROJECTS • 2010-2011: Designed both hardware and software of obstacle detector which performed well by detecting the obstacles which come into its path and then turning into either right or left hand side. • 2012: Implemented receiver algorithms on a DSP board. Algorithms included filtering, demodulation, synchronization, error detection and message display using MATLAB. • 2012: Implemented an FIR filter on an FPGA chip using Quartus Altera software. • 2012: Implemented a wireless sensor network using ZigBee enabled PIC nodes. Functionality included CSMA/TDMA network protocol, error detection, temperature/light sensor interfacing and analog input to digital output conversion. • 2012: Implemented Advanced modulation and demodulation techniques using MATLB. • 2013: Mitigating the effects of cross channel interference on a ZigBee based Wireless Sensor Network. Algorithms that enable ZigBee based networks to effectively determine the severity of the interference. • 2013: Worked on colour constancy algorithms and developed a MATLAB code which works better than many previously proposed algorithms.
