Method or switching assembly for identifying a symbol when receiving a signal coupled with a quadrature signal pair

摘要

The method involves in decision-making by analyzing metrics of a reception point to a reference point in complex co-ordinate areas. The metrics is analyzed in a non-complex or non-exclusive Cartesian complex coordinate areas. A reliability of the decision-making is obtained during a decision-making process. The decision-making is considered in a polar co-ordinate area. A Euclidean distance between the reception and reference points is provided as the metrics and/or the values of angle and radius projections of the metrics are analyzed between the reception and reference points.
