BPSK BER and SNR Simulation using Simulink MATLAB R2013a

Practicum of BPSK, QPSK, QAM 16, and QAM 64 modulation and demodulation using MATLAB R2013a Software-Based Simulink has been done. Simulations are carried out using the existing toolbox in Simulink. This simulation was carried out in order to study the chapter on the introduction of Digital Modulation and Signal Processing Engineering courses, which was supervised by Mr. Bambang Bagus Hariyanto as the lecturer of this course. The execution of this simulation aims to describe how the characteristics of the waveform of each block modulator and demodulator block. So that the students can truly understand and appreciate clear picture of the work process of sending and receiving digital modulation and demodulation techniques BPSK, QPSK, 16-QAM, and 64-QAM.This study makes the program on each block of modulator and demodulator on each technique BPSK modulation and digital demodulation and QPSK. The accuracy of testing to the extent of the program on each block. The test is successful when the binary input according to the binary output affected by noise AWGN and when changing the shape of the signal at AWGN deviation.
