Abstract :
In part I the theoretical foundations of a new class of area-efficient architectures for the Viterbi algorithm were established. Area-efficient architectures for practical codes are presented here to illustrate the design procedures and demonstrate the favourable area-time tradeoff results. Three examples from convolutional codes, matched-spectral-null (MSN) trellis codes, and Ungerboeck codes are presented. The application of the area-efficient techniques to codes with a very large number of states, codes with time-varying trellises, and a programmable Viterbi decoder is discussed
