Hi.
Can anyone please tell me if I design a 4 user co-ofdm gigabit passive optical network, and my data rate is 15Gbps, how much the symbol rate should be? I have divided 15/4users and its 3.75symbol rate. is this a correct way to get the symbol rate?
Kindly help me out.

Thanks.

      Hello Kam,
      What modulation scheme are you using before using OFDM? That would affect the symbol rate.

      they you need to divide the bit rate by 4 to get the symbol rate.
