hello Damian Marek ,
thank you very much for your help , but i have tow issue :
1- for the first file ( LTE-64QAM ) that i attached above it is worked as 16QAM not 64QAM , I i want to run it in 64QAM but it didnt give me the right result as the 16QAM did .
2- for the second file ( LTE-QPSK ) i cannt open it , and i am using optisystem version 13 , it give me error massage i will attached it below , also i want to run the simulation on (2.6 GHz) frequency because the LTE system use this frequency .
i hope you nwill help me again please .
