Transceiving pilot frequency diagram numerical control communication link based on cross-frequency frequency hopping technology

The invention provides a pilot frequency diagram receiving and transmitting numerical control communication link based on a frequency-crossing frequency hopping technology, relates to the technical field of wireless communication frequency hopping, and effectively solves the problem of response lag when the signal quality change is large by introducing an adaptive observation window and a quality index evaluation mechanism. Specifically, the system can dynamically adjust the length of the observation window according to the change of the spectrum amplitude, the signal intensity and the noise intensity, and selects the optimal frequency unit for frequency hopping by calculating the signal-to-noise ratio and the quality index of the frequency unit. The mechanism not only improves the stability and reliability of a communication link, but also remarkably improves the utilization rate of spectrum resources, and reduces frequency occupation conflicts and communication interference, thereby realizing more efficient
