Convolutional coding [Under GSM > Full rate speech coding illustration]
Convolutional coding is applied to reordered 189(=50+132+3+4) bits, 1/2 rate coding with following formulas (Ref 45.003:3.1.2.2):
G0 = 1 + D
3 + D
4
G1 = 1 + D + D
3 + D
4
D
y is cyclically shifted (by
y bits) version of original bit sequence.
G0 and G1 (189 bits each) are put together (G0 at even bits and G1 at odd bits) as below.
