International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / This paper introduces a PPK intelligent
demodulator used in the PCM--PPK (pulse position keying)
telemetry system. It describes the basic requirement of the
system for the PPK signal demodulator and analyses the
insufficiancy of the full-hardware PPK demodulator. It also
advances a PPK demodulating scheme based on the TMS32020
digital signal processor and a block diagram of the
demodulator, states the method of detecting frame
synchronization, analyses the precision of sync-building and
gives the way of calculating the miss and error probability
of frame sync. The result makes it clear that the
demodulator based on TMS32020 has programmable feature for
the bit rate and frame synchronization and realizes easily
the system demand of the separate demodulating of output
signals of the multi-channel receiver and then the synthesis
processing of the realtime data.
