Abstract

Several new algorithms for decoding lattice partitions are presented. They apply to Viterbi decoding of multidimensional trellis codes based on these partitions. In [1, 2], trellisbased algorithms were presented for decoding the lattice partitions. The new algorithms can achieve about 50% reduction of the complexity of decoding the lattice partitions in terms of real additions/comparisons compared with the algorithms of [1, 2]. The complexity of the resulting overall Viterbi decoding algorithms still shows a modest improvement. An algorithm for soft decision decoding the first-order Reed-Muller code (8, 4, 4) or the Gosset lattice is also presented. It involves at most 17 real operations, thus, improving the best known algorithm.
