Coherent QPSK simulation and BER vs. SNR curve

version 1.0 (2.02 KB) by

BER performance for QPSK over additive white Gaussian noise channel is estimated and plotted.



View License

This program performs a Monte Carlo simulation of a coherent QPSK communication system and plot the error probability performance over additive whit Gaussian noise channel. The detection is based on correlation metric. Simulation is performed for 10,000 bits and measurements are made accordingly.

Hi, we only need to change from "Qfunc" to "qfunc" to fix this.

hi sanjeet, i cant run your QPSK simulation file, there is an error in this line theorerrprb(i)=theorerrprb(i)+Qfunc(sqrt(2*SNR))

perhaps do you know why? thx...

hi nice
