    hello Ranjeet,
    the problem is very clear and its :
    the RF spectrum analyzer and electrical carrier analyzer did not give the same value for signal power as the pic show.

    actually i used electrical power meter and its result was more closer to the electrical carrier analyzer results
    but the question is how can we get the same results and why this happened
    thank you again for your helping

    hello,
    i am using optisystem 13 32-bit to design OFDM radio over fiber system that carried LTE signal over fiber optic channel and i am facing aproblem in getting a big BER value ( 0.33 ) and low Q factor but clear constellation diagram , even when run the simulation without any fiber channel (( only modulate and demodulate )) it still give me the same BER value without any change , i hope you to give me the reason why that happened and how can i get the right BER that depending to the channel .
    thank you very much
