| An important problem in the theory and application of block code trellises is to nd a coordinate permutation for a given code that minimizes the trellis state complexity. In this paper we show that the problem of minimizing a given component of the state complexity proole is NP-complete. We describe an algorithm, though not guaranteed to nd an optimal coordinate ordering, uses a heuristic descent technique to nd \good" solutions to the problem. We have applied this algorithm to various codes, and our results are tabulated.
