Abstract: | Based on the theory of phase-locked loop, the analysis and simulation of direct frequency shift keying to phase-locked oscillator
is presented. Then, a W-band digital communication system is developed, in which the millimeter wave phase-locked oscillator
of the transmitter is modulated directly by 15grades 2048 kbit/s signal. The results of the experiment in the field show that
the phase-locked loop has little influence on the modulating signal. It is a good way to simplify the transmitter configuration
and suitable for high bit rate communication. |
