BER simulation of a digital bandpass QPSK modulation system matlab program. The simulation system either bandpass or baseband communication system, a communication error rate calculation process system model parameters set primarily by creating a signal, i.e., the source coding, modulation, Gaussian noise is added to the modulated signal, a demodulator, a computing system BER and other steps. This example describes in detail how to use matlab communication toolbox provides functions to achieve BER simulation system.
