| Description |
A stack-based sequential depth-first decoder that returns Maximum-Likelihood solutions to M-QAM modulated MIMO system-type problems, i.e., a lattice decoder with optional justified rectangular boundary control. In such problems, the depth of the search tree is known and the number of children per node is also fixed.
Real or complex inputs are permitted. The depth-first search is effected by applying the Schnorr-Euchner (Adaptive radius) enumeration to traverse the nodes of the tree.
Please see the function pre-amble (type `help SEA_det` at the Matlab prompt) for more details. |
