Abstract
The present disclosure discloses a device, system and method for bi-phase modulation decoding. The bi-phase modulation decoding device includes a sliding-window module and a determination module. The sliding-window module is configured to receive a baseband signal corresponding to a bi-phase modulated signal, and generate a filtered data packet by filtering the baseband signal using sliding-window digital filtering, wherein the filtered data packet comprises a series of sliding-window output values. The determination module configured to determine a bitstream corresponding to the bi-phase modulated signal based on the filtered data packet. The determination module determines a bit value of a first bit cycle of the bi-phase modulated signal based on a sign of a sliding-window output value of the first bit cycle and a sign of a sliding-window output value of a next bit cycle.
