Thank Mr Alessandro Festa.. So, PRBS only generates the bit sequences, the value is true (1) or false (0), isn’t it ?
When the output PRBS is connected to QAM Sequence generator and then both of QAM Sequence outputs are connected to OFDM, we can measurement the electrical power in output of OFDM.. I have some difference power value if i use 4 QAM and 16 QAM. Please give me explanation, where the power in step could be present ? from QAM or OFDM ?
Thank you before,
