abstract = "In this paper, we present the design of a fully digital binary
phase shift keying demodulator for application in satellite
high-rate suppressed carrier telecommand system. The proposed
system digitalizes the received signal in the intermediate
frequency stage using bandpass sampling technique, and the
resulting baseband signal is used to synchronization of symbol and
phase and to bit detection. The design of all functional modules
is presented in details. Another innovation presented in this work
is the inclusion of a non-linearity in the phase synchronizer
module to permit its operation independent from the signal
amplitude. Moreover, aiming the characterization and performance
evaluation of the system, we do some original mathematical
analyses. Finally, test results show that the demodulator complies
all the project requirements, and the prototype implementation
loss, in terms of bit energy to noise power density ratio, is less
than 0.3 dB.",
