Simplified detection method using spheres in the presence of a low signal-to-noise ratio

摘要

The method of detection of a number of symbols transmitted by users has each symbol used modulated in a modulation network. The detection method generates a sub assembly of network points characterizing the signal. There is a step of orthogonal projection of the point received in the refined sub space called parallel projection and a step of refining the nearest projected point amongst the constellation points.
