Abstract
Design criteria for trellis codes with sequential decoding are examined. A comparision of trellis codes with Optimum Distance Profile (ODP) and Optimum Free Distance (OFD) reveals that neither ODP nor OFD trellis codes result in the best trade-off between error performance and computational performance when sequential decoding is used. A new approach is proposed to construct robustly good trellis codes for use with sequential decoding. The new codes obtained using this approach achieve nearly the same free distances as the OFD codes and nearly the same distance profiles as the ODP codes.
