A multistage projection structure for multidimensional signal detection

A multistage projection detection structure that for one example is demonstrated to yield significantly higher sensitivity than single-stage projection is proposed. Instead of projecting many samples onto one sample in a single step, the projection is done in stages. Prior to each stage, filtering is done to enhance the signal-to-noise ratio as much as possible. The more signal samples there are in a single frame of input data, the greater the potential increase in detection sensitivity. The structure´s usefulness for a particular application will depend on the number of samples of the signal contained in a single frame as well as implementation costs
