Embodiment Construction
[0046] Step 1, define the original sequence H 0 .
[0047] To generate the final frequency hopping sequence, the original sequence needs to be given, and the original sequence is H 0 ={s 0 (j)},s 0 (j) represents each original symbol in the original sequence, set 0≤s o (j)≤rq, r is the compression factor, and q is the number of frequency slots of the system.
[0048] Step 2, define the weight w f .
[0049] Each original symbol s in the original sequence o All values of (j) are defined as the set F 0 , F 0 Each symbol in is called a mapping source, when for the set F 0 When performing compressed mapping, multiple mapping sources are used to correspond to a frequency hopping frequency number, and each frequency hopping number corresponds to the number of mapping sources with a weight w f Indicates that f represents the frequency hopping frequency number 0≤ff Instead of the occurrence probability of each frequency hopping number.
[0050] Step 3, determine the initial...
