Mimo Sphere Detection with Parallel Distributed Node Processing
The present invention is related to method for detecting a symbol transmitted over a communication channel in a multiple input-multiple output communication system by performing sphere detection. A parallel processing performing a distributed-greedy-algorithm for the tree search is proposed. It is based on a local minimization at each node of an increment of the Partial Euclidean Distance. Further the number of children expanded from a node is limited to a constant, independent from the constellation size.
