lambda 2/1 # whereas for a rate 1/4 code, lambda 4/3 # # All measurements are made in units of M. All cartesian coordinates # are (horizontal,vertical) # # subsequent lines are either block commands or control commands. # # block commands come in two flavours: # Identity blocks: # 6x3 I 1/3 at 0/1,0/1 1x1 I 1/1 at 0/3,0/1 1x1 P 1/1 at 3/3,0/1 # and Permutation blocks: # 5x2 P 1/3 at 1/3,1/3 # 1x2 I 1/2 at 0/1,0/1
