Abstract
A method, a system, a wireless device and a computer program product are provided. A process for decoding transmitted symbols in MIMO systems is provided. The received point coordinates and estimated candidate coordinates are represented by a reduced bit representation naturally dividing each dimension into uniformly sized bit segments. A bounded region surrounding the received point is defined in the total number of dimensions, the bounded region being a hypercube. For each candidate, an elimination process is carried out including: determining a position of the candidate to be inside or outside the bounded region, eliminating the candidate if it is outside, storing it if it is inside, adding a further bit thereby reducing a size of the bounding region; repeating the elimination process for the candidates stored as potential solutions until a single solution is obtained; determining the transmitted symbols from the single solution found.
