Abstract (Summary)
This thesis focuses on the modeling and simulation of the performance of M-ary modulation techniques. In addition to the most popular used coherent modulation schemes, forward error correction (FEC) coded signals, and fading channels are also considered. The channel is modeled for the two cases of fading and no fading, both with additive white Gaussian noise (AWGN). The effect of barrage noise interference is also considered. Binary phase-shift keying (BPSK), 16-PSK, and 16-QAM (quadrature amplitude modulation) communication systems are simulated and analyzed. For BPSK, both hard decision decoding (HDD) and soft decision decoding (SDD) are considered. For 16-PSK and 16-QAM, only HDD is examined. Simulation results and analytical results are compared. The results show that the modeling and simulation in SystemView, are in excellent agreement with the analytical results.
