10.2 False alarm probability of AWGN channel- False alarm probability (Pfa) is probability which detects unique word after PHY Header.- Pfa = 9.91 x 10-3 (at 156 Mbps), 3.91 x 10-2 (at 624 Mbps)- Calculation of Pfa is as follows

Pfa_1ch = 0.520 x 10395= 9.91 x 10-3

20 = unique word length10395 = (length from PHY Header to FCS with including FEC per 1ch)

Pfa = 1 - (1 - Pfa_1th ch) (1 - Pfa_2nd ch) (1 - Pfa_3rd ch) (1 - Pfa_4th ch)It is assumed that Pfa_1th ch = Pfa_2nd ch = Pfa_3rd ch= Pfa_4th ch

Pfa=1 - (1 - Pfa_1ch)4 = 1 –(1 – 9.91 x 10-3)4 = 1.02 x 10-2

•When the desired rate is greater than 156 Mbps, it could be provided by changing number

of channel.

•When the desired rate is smaller than 156 Mbps, it could be provided by symbol repetition .
