    Hello Fayiqa,
    System margin is set to ensure that small variation in the system operating parameters do not result in an unacceptable decrease in system performance. I have attached two snapshots. One contain formula to calculate power budge and the other contains an example for this calculations.
    hope this information will help you out.
    Regards,

    I have one more question. If I design a system using 16-QAM. Now I want to analyze or compare the results for 64-QAM or 4-QAM, what valuse or variables need to change to make the system work for these modulation formates? and what If I want to get result for QPSK. I am working of Direct Detection OFDM.
    Thanks in advance.
