Abstract :
A new general criterion for the optimal design of (possibly) time-varying and nonlinear trellis-codes for reliable transmission of digital information sequences over arbitrary (possibly) time-varying discrete memoryless channels (DMCs) is presented. The criterion is derived on the basis of new tight generally time-varying analytical upper bounds developed for the performance evaluation of MAP decoders with finite decoding constraint-lengths which minimise the symbol-error probability. New procedures related to the proposed criterion are also presented, allowing a direct construction of good trellis-codes for any arbitrary DMC and for any assigned value of the decoding constraint-length
