摘要: A method includes receiving a symbol modulated with multiple bits according to signal constellation including points. soft metric is computed for given bit in the symbol: first point closest received distance measure found. row or column of points, which measure, and over value constant opposite point, identified. At least identified searched second that measure. The calculated based on reconstructed metric.
