Abstract
A non-coherent receiving system is provided with a novel triple-bit matched filter detector system which provides two outputs indicative of the data stream being detected. A preliminary or soft decision is made concerning the state of the bits in the data stream. One of the outputs provides a best estimate of state of the data bit being detected and the other output provides the second best estimate of the state of the data bits being detected. The incoming data stream is processed and modified as it is shifted through a plurality of shift registers in real time employing the data bits subsequently detected. A controller is provided to make a plurality of predetermined evaluations of the state of the bits in the data stream and to provide a final or hard decision of the correct state of the data bits previously detected.
