Qam and qpsk modulation for FSO

01 January 1970 1 2K Report

i want to do simulation for free space optical communication with using qam and qpsk modulation how can i do ?

if any one know how to do qam modulation for fso and qpsk modulation for fso by using optisystem . please help me

I. To simulate FSO underground train system based on QAM and QPSK modulation techniques.

how can i do qam and qpsk modulation with using this design so i need to change NRZ to QAM/QPSK . Anyone can help me for this simulation . I will send you my file of simulation
