The following formula can be used to calculate the actual hopping
sequence:
P (i)=P [(i+s-1)mod(N)+1]
S 0
Where:
S is the hopping shift
N=number of channels in the sequence (modulus)
P (i) is element number i in the actual sequence with hopping shift s
S
P (i) is element number in the basic hopping sequence (s=0).
0
For example, in the basic sequence with N=6:
P (1) =1
0
P (2)=3
0
P (3)=5
0
P (4)=2
0
P (5)=6
0
P (6)=4
0
For a shift of 3, the actual sequence is:
P (1) =P [(1+3-1)mod6+1]=P
3 0
P (2) =P [(2+3-1)mod6+1]=P
3 0
P (3) =P [(3+3-1)mod6+1]=P
3 0
