QPSK_demodulate.m (385, 2004-04-11)
This is a Matlab program and functions to simulate the bit error rate of QPSK. To run this program put the following 3 files in the same folder:
QPSK.m
QPSK_demodulate.m
QPSK_modulate.m
Make this folder the working folder of Matlab. Then type: PAM8 in Matlab work space. The program takes about 30 to 40 minutes, depending on your computer. It plots the SER versus the SNR per symbol in dB, and the BER versus the SNR per bit in dB. It also generates the two plots as jpeg files.
