• Designed the schematic of the frequency synthesis with a 50MHz reference signal and 200MHz output signal based on phase locked loop by Cadence
• Simulated the schematic and analyzed the output performance
• Designed the layout by Cadence Virtuoso

• Designed open/close loop boost converter circuit, including the inductor and PWM (Pulse-width modulation) driving circuit parameters
• Soldered the circuit and tested the open-loop and close-loop circuit with different input voltage and output power and computed the system efficiency

• Compared convergence performance of two adaptive linear equalization by Matlab
• Used LMS (Least Mean Square) algorithm with different delta (0.0550, 0.0275, 0.0138) and RLS algorithm with different lambda (0.9,0.7,0.5 ) to see performance differences

• Simulated the bit error rate performance of a regular LDPC (Low-density parity-check) code over an additive white Gaussian noise (AWGN) channel, including encoding and decoding by Matlab
• Simulated the bit error rate performance of a convolutional code with different values of the probability of BER in the BSC(Binary symmetric channel) by Matlab

• Simulated various modulation methods by Matlab, including MQAM, MSK, and binary FSK
• Compared their BER versus SNR performances and power spectral density performances of different parameters
