Thus octal 5111 corresponds to thegenerator polynomial 1 + x 3 + x 6 + x 9 + x 11 .** The initial condition is given as n 11 , … , n 1 . (See Figure 3.2-2)†The initial bit value 0 is dropped to obtain 11 symbols. Thus octal 3035 corresponds to 11values 1 1 0 0 0 0 1 1 1 0 1.109 IS-GPS-800A8 June 2010
