Control circuit for improving DSRC radio frequency communication efficiency and control method thereof

Abstract

The invention relates to the field of DSRC radio frequency communication, and in particular to a control circuit for improving DSRC radio frequency communication efficiency and a control method thereof. The control circuit comprises an LC oscillation module which is used for generating a high-frequency sine wave signal by a DSRC circuit, and the continuously consumed oscillation signal is fed backand amplified by various signal feedback methods, so that a signal with relatively stable amplitude and frequency is finally output; a shaping and amplifying module which is used for shaping and amplifying the DSRC radio frequency communication signal so as to convert the DSRC radio frequency communication signal into a same-frequency square wave signal, so that the output signal is more stable;a signal input module which is used for inputting DSRC radio frequency communication; and a radio frequency modulation module which is used for transmitting the frequency spectrum of the baseband signal to a higher carrier frequency, and meanwhile, a plurality of baseband signals can be transmitted to a plurality of different carrier frequencies, so that multiplexing is realized, and the transmission efficiency is improved; the radio frequency monitoring module is used for observing the output radio frequency signal, so that the frequency stability of the DSRC radio frequency communication signal can be ensured; according to the control circuit, the radio frequency signal frequency is better stabilized.

AI Technical Summary

Problems solved by technology

[0004] The DSRC radio frequency communication in the prior art is working, the signal frequency is unstable, the frequency waveform fluctuates greatly, and the oscillating signal inside the circuit will be continuously consumed, so the output amplitude is very different from the frequency, so the equipment does not work well. Stable, and in transmission, the baseband spectrum of the signal cannot realize one-to-many working mode, thus reducing work efficiency
