In this thesis, we attempt to decrease the decoding complexity of self-orthogonal tree-structure codes designed for combined channel estimation and error correction by fitting them into a trellis structure subject to an upper bound on the number of trellis states at each level. Specifically, we provide an algorithm to compress the tree-structure codes into a trellis structure by selectively merging tree nodes. Simulations show that the more the merged nodes, the less the memory consumption and decoding complexity, but the worse the performance. A trade-off among these factors can therefore be controlled by a proper choice of maximum number of trellis states.
