Abstract
The Pruned Tree sigma-delta modulation algorithm is a further refinement on the algorithms that are described in the previous chapters. This algorithm is a practical realization of the pruned look-ahead approach as derived in chapter six. A total of M paths are tracked, with no constraints on the solution space coverage imposed. The result of this approach is that a performance level that is slightly better than that of the Efficient Trellis sigma-delta modulation algorithm is realized, at a significantly reduced computational load. In the chapter not only the algorithm is detailed, but also the functional performance is extensively studied and important details for an efficient implementation are discussed.
