To solve the problem of wrong data setting because RF setting system is susceptible to the impact of noise and interference, a scheme that encode the work command on the end of setting system is proposed to enhance the anti-jamming capability of the system. Firstly, according to the linear relationship between information bits and oversight bits of (7,4) cyclic code, work command is encoded into error control coding, so work command has the ability to detect and correct an error bit. Secondly, the use of balanced Gold code to spread spectrum modulation make the system with the advantage of strong confidentiality. Finally, based on the design of the sinusoidal signal generator in look-up table method, conducting QPSK modulation in choice method, which has a simple structure and easy to realize. The experiments prove that using 31 bits balance Gold code to DSSS modulate, system can gain for 14.77dB; the frequency of QPSK waveform is 781.25 KHz, all meet the design requirements.
