Dear all , i am working in coherent OFDM , in optisystem 12 under optisystem 12 samples –> advance modulation systems —> OFDM systems — > ( all the examples listed ) coherent detection optical OFDM system as an example , when we calculate the example and read the BER analyzer , the reading value is zero , when i tried to sweep the optical length also i get the same value , when i tried to read the BER from all the examples also it gives me zero value for min BER

any one can help me in this problem ?
