Abstract Generalized Spatial Modulation is a recently developed technique that designed to enhance the efficiency of transmissions in MIMO Systems. However, procedure for correctly retrieving sent signal at receiving end quite demanding. Specifically, computation maximum likelihood solution computationally very expensive. In this paper, we propose parallel method using computing library OpenMP. The proposed algorithm computes faster than sequential version, and substantially reduces worst-case times.
