Abstract
In telemetry communication, it is crucial to establish correct frame synchronization, a scheme for applying optimal frequency hopping patterns to aerospace telemetry communication systems is proposed, and the architecture of the transceiver system is given. Compared to one-dimensional pseudo-random sequences, optimal frequency hopping patterns have ideal two-dimensional autocorrelation and cross-correlation performance, which can effectively reduce or eliminate the interference caused by delay and Doppler shift and solve the problem of unable to synchronize frames that is caused by low signal-to-noise ratio and strong interference.
