Abstract:
A method for encoding a digital signal which is compatible with a rate-1/l convolution code decoder, said method comprising:selecting a base convolutional encoding rate of a rate-1/l, where l is an integer;selecting an output convolutional encoding rate of 1/n, where n is an integer greater than l;encoding an input digital signal into a rate-1/l convolutional code comprised of a plurality of signals S(0) through S(l-1); andencoding said rate 1/l convolutional code into a rate-1/n convolutional code, said rate-1/n convolutional code having N(i) copies of said rate-1/l signals S(i), where i is from 0 through l-1 and where the sum of N(i) equals n.
