A convolutional encoding device and method in a digital system. According to an embodiment of the present invention, a convolutional encoding device has a convolutional encoder and a puncturer. The convolutional encoder generates a subgroup of a first, a second and a third encoded symbols for each input bit using generator polynomials including g0(x)=1+x2+x3+x5+x6+x7+x8, g1(x)=1+x +x3+x4+x7+x8, and g2(x)=1+x+x2+x5+x8, for inputting input bits to generate a symbol group of three subgroups for three successive input bits, and for generating a stream of the symbol groups. A symbol puncturer punctures the first symbol of one of three subgroups in each symbol group generated from the convolutional encoder. |
