....C. Range of Encoders to Search Without concatenation, searching for good trellis codes that maximize free distance requires examining only one code within each group of range equivalent encoders. Two encoders are called range equivalent if they have the same set of possible output sequences [10] (Forney s notion of equivalence) So, it is sufficient to restrict attention within a set of canonical encoders, which are identified by Forney [11] For turbo codes, the mapping from input to output sequences plays an important role. Range equivalent codes can have quite different performance. ....
....values. IV. SIMULATION RESULTS This section provides simulation results for 2 bits s Hz employing 16QAM and 8PSK and 4 bits s Hz employing 64QAM 2 8 PAM. Table III contains in octal notation codes identified through computer search, and optimized for normalized with the edge profile optimal [10], 16] constellation labelings illustrated in Fig. 5. Our search over all interesting constituent convolutional encoders mapped onto the chosen labeling, in fact, produces all interesting constituent codes that could be found with any other labeling related to the chosen one by a binary linear ....
