Abstract :
A code tree for a rate 1/3, memory-2 turbo code is developed and shown to have a nonuniform branch structure due to the effect of the interleaver. The tree is used to compute the weight spectrum, and the number of terms required for an accurate upper bound to the bit error rate are identified
