- Python Windows
- Linux Graduate Level Projects : Physical Layer Simulation of a Simplified LTE OFDM Estimated path loss And received power for various models such as Free space
- Simplified path loss
- 2 ray ground reflection model
- COST231 model And thus developed a path loss simulator in MATLAB. Developed Rician fading And Frequency Selective fading simulators for a mobile communication channel. Generated BPSK
- QPSK
- 16-QAM signals And Bit Error rate ( BER ) simulations of all these 3 schemes were done in AWGN channel
- Rayleigh fading channel And finally with two-antenna transmit diversity using Alamouti transmission scheme. Implemented OFDM Modulator And Demodulator for various modulation schemes such as BPSK
- QPSK
- 16-QAM in the presence of AWGN And various multipath channels. Adaptive Modulation was done based on the received Signal to Noise Ratio ( SNR ) to achieve lower Bit Error Rate ( BER )
- And finally performed MIMO OFDM Simulation. Design of an Octave Bandwidth feedback MMIC Amplifier on GaAs Designed a Two Stage ( 0.7 Ghz-1.4 Ghz ) MMIC Amplifier on GaAs substrate to have a gain of more than 20dB
- K ( Stability factor ) 1
- And return loss = 10 dB. FH101 TriQuint MESFET S-parameters were used for the design. Design of a Microstrip Patch Antenna on Duroid Designed a Microstrip Patch Antenna on Duroid substrate in the frequency range of ( 0.89 Ghz - 0.91 Ghz ) to have a return loss of greater than 10 dB Characterization of ML485 Mixer Triquints ML485-G Mixer with LO Amplifier characteristics performance was observed And measured. VNA
- Signal generator
- spectrum analyzer were setup And connected to the mixer circuit via RF Cables. The key parameters of Mixer like Return Loss
- Cable Loss
- Isolation
- Conversion Loss were measured. At frequency of 2.2GHz by varying LO Signal Power Level ( dBm ) conversion loss was measured. Design of a Two-Stage Broadband RF Amplifier Designed a broadband amplifier that is utilized as a front-end amplifier for optical receivers using AWR MWO Design was done using DC Analysis
- AC Analysis
- And Stability Analysis. Using AWR MWO
- the amplifier circuit was designed And the performance was checked for stability
- the bandwidth calculated was 600 MHz. Design of a Two-Stage Low Noise Amplifier at 10 GHz Designed a 2-Stage low-noise Amplifier ( LNA ) by applying the RF And Microwave Concepts using 2 transistors which are both NEC710. Using AWR MWO each matching network was designed using Microstrip lines. The measured performance parameters are Center Frequency = 10 GHz
- Noise Figure=1.668 dB
- Output Return Loss=14.55 dB
- Gain=19.26 dB. FIR Filter Design And DTMF Transmitter/Receiver Design Developed a usable software package to design linear phase FIR filters using windowing techniques. Designed a dual tone multi-frequency ( DTMF ) transmitter And receiver with implementation of Oscillator to generate the required frequencies in the encoder part And the decoder can detect the keys transmitted using a bank of narrow band pass filters which is implemented using resonators.
