Embodiment 1
[0041] A. In the 433MHZ frequency band, select 35 different frequency points and arrange them in order to obtain the frequency point list T, and serial number each frequency point according to the order of arrangement;
[0042] B. Select a group of prime numbers, after the arrangement is completed (7, 11, 13, 19, 23, 31, 37, 41, 47... such prime numbers), form a one-to-one correspondence with the arranged frequency points;
[0043] C, the prime number p is multiplied by the serial number i of the corresponding frequency point, then divided by the total number of frequency points and the remainder is taken, and the frequency point whose sequence number is the remainder in the frequency point list T is used as the frequency point in the new frequency point list L The frequency point whose serial number is i;
[0044] D. Repeat step C until a complete list L of new frequency points is obtained.
[0045] In the new frequency point sequence L generated in this way, frequency points ...
Embodiment 2
[0047] A. In the 470MHZ frequency band, select 60 different frequency points and arrange them in order to obtain the frequency point list T, and serial number each frequency point according to the order of arrangement;
[0048] B. Select a group of prime numbers, after the arrangement is completed (7, 11, 13, 19, 23, 31, 37, 41, 47... such prime numbers), form a one-to-one correspondence with the arranged frequency points;
[0049] C, the prime number p is multiplied by the serial number i of the corresponding frequency point, then divided by the total number of frequency points and the remainder is taken, and the frequency point whose sequence number is the remainder in the frequency point list T is used as the frequency point in the new frequency point list L The frequency point whose serial number is i;
[0050] D. Repeat step C until a complete list L of new frequency points is obtained.
[0051] In the new frequency point sequence L generated in this way, frequency point...
Embodiment 3
[0053] A. In the 915MHZ frequency band, select 64 different frequency points and arrange them in order to obtain the frequency point list T, and serial number each frequency point according to the order of arrangement;
[0054] B. Select a group of prime numbers, after the arrangement is completed (7, 11, 13, 19, 23, 31, 37, 41, 47... such prime numbers), form a one-to-one correspondence with the arranged frequency points;
[0055] C, the prime number p is multiplied by the serial number i of the corresponding frequency point, then divided by the total number of frequency points and the remainder is taken, and the frequency point whose sequence number is the remainder in the frequency point list T is used as the frequency point in the new frequency point list L The frequency point whose serial number is i;
[0056] D. Repeat step C until a complete list L of new frequency points is obtained.
[0057] In the new frequency point sequence L generated in this way, frequency point...
