Dear friends
Hope you all will be fine
I need your help in an issue
I am transmitting 4×2 Gbps RF data signals by ASK modulation over fiber for radio over fiber transmission where multiple access is implemented by DS-SS.At TX side, i am XOR each bit streams with PN sequence. what should be the data rate of PN sequence??? and the PN sequence should be simply generated by PRBS generator????How can i check orthogonality of long PN sequence generated e.g 2 Gbps PN sequence rate??
Please check a reference paper attached where the author did not mentioned how he generated PN sequences, PN data rate and it orthogonality.
Please guide and help me in this regard
i am highly obliged.
