Embodiment Construction
[0009] A method for realizing frequency hopping synchronization based on time information, comprising the following contents:
[0010] This algorithm uses a truncated TOD recovery algorithm to realize TOD frequency hopping synchronization. Practice shows that this algorithm can realize fast synchronization between the sending and receiving ends, and the air transmission data volume is small and the confidentiality is strong.
[0011] Table 1 TODh structure
[0012]
[0013] The existing TODh does not need to restore the algorithm, and can directly correct the local TOD information according to the originating TOD information.
[0014] The existing algorithm divides the 40-bit TOD information into two sections: TODh(25bits) and TODl(15bits):
[0015] TODh format: Bit39Bit38...Bit17Bit16Bit15
[0016] TODl format: Bit14Bit13...Bit2Bit1Bit0
[0017] Generally, TODh is used to represent year, month, day, hour, minute, and second, while TOD1 increases by 1 according to each j...
