Zusammenfassung:	One embodiment of the present invention includes a decoder system that decodes a bi-phase modulated signal to generate an output code. The system includes a first filter associated with a first logic state configured to generate a first dot product of a plurality of consecutive digital samples of the bi-phase modulated signal and a respective plurality of tap weights of the first filter. The system also includes a second filter associated with a second logic state configured to generate a second dot product of the plurality of consecutive digital samples of the bi-phase modulated signal with a respective plurality of tap weights of the second filter. The system further includes a comparator configured to compare the first and second dot products and to provide the output code as a bit having one of the first logic state and the second logic state based on the comparison.
