    Well actually what you are explaining here is CNR or carrier to noise ratio and the relation to eb to no. SNR or signal to noise ratio is something different. CNR and SNR are related but slightly different metrics used to assess the quality of a communication system. CNR is specifically focused on the ratio of the received carrier signal power to the noise power, while SNR considers the ratio of the desired signal power to the noise power. CNR emphasizes the carrier signal, while SNR encompasses the overall signal quality.

    Thank you so much Prof.Leslie Rusch; Please I have an important question regarding radio over fiber transmission; By simulation, I transmit 1.5 Gbps wired signal with two 65 Mbps 8/16 PSK OFDM signals at 2.4 GHz using the same optical carrier over 30 Km SMF. The used modulation is optical double sideband with carrier (the wired is carried on the optical carrier 193.1 THz), while 8 or 16 PSK OFDM signals on the sidebands. When I measure the wired signal BER at different access distances such as 22, 24, up to 30 km; constantly always 8 PSK-OFDM signals get better performance then 16 PSK-OFSM signals even although they operates under the same simulation conditions ( launch power 12 dBm). Why? I can't get any logical interpretation of this result. Please, could you have any idea about that or precision, I'll so thankful to you; your response means to me a lot. Best regards.
