Embodiment 1

[0089] As shown in Figure 4, Figure 4 is the flow chart that the present invention produces extended Latin square sequence, comprises the steps:

[0090] S401. Generate an N×N Latin square matrix according to a given prime number N and specified parameters;

[0091] S402. Add a column before the first column of the N×N Latin square matrix to form an extended Latin square matrix of N×(N+1);

[0092] S403, making each element of the added column identical to each element of the first column of the original Latin square matrix;

[0093] S404. Adjust the element values ​​in the extended Latin square matrix, so that the element values ​​of the extended Latin square matrix are extended to 0 to N;

[0094] The specific adjustment method is that the value of each element is recalculated according to the following formula:

[0095] B α (i,j)=(A α (i, j)+j) mod (N+1), 0≤i, j≤N

[0096] Among them, B α (i, j) is the adjusted element value, A α (i, j) is an element value be...

Embodiment 2

[0102] As shown in FIG. 7, it is a flow chart of performing frequency hopping communication control according to the method described in Embodiment 1, including the following steps:

[0103] S701. Obtain the number of frequency points M of the system and the cell index α for performing frequency hopping control, and calculate N=M-1, where N is a prime number;

[0104] S702. Generate a corresponding N×N Latin square matrix according to the prime number N and the cell index α;

[0105] S703. Add a column before the first column of the N×N Latin square matrix to form an extended Latin square matrix of N×(N+1);

[0106] S704, making each element of the added column identical to each element of the first column of the original Latin square matrix;

[0107] S705. Adjust the element values ​​in the extended Latin square matrix, so that the element values ​​of the extended Latin square matrix are extended to 0 to N;

[0108] The value of each element is recalculated according to the...

Embodiment 3

[0120] As shown in FIG. 8 , the structure of an extended Latin square generator 800 implementing the method described in Embodiment 1 includes:

[0121] Latin square family square matrix generating unit 801, for producing corresponding N×N Latin square family square matrix according to given prime number N and specified parameters;

[0122] Extended Latin square family sequence generation unit 802, connect described Latin square family square matrix generation unit 801, for producing N * (N+1) extended Latin square family matrix according to N * N Latin square family square matrix Latin square family And according to the specified column number information, the extended Latin square family sequence of the corresponding column is output, and any two columns in the N×(N+1) extended Latin square family matrix are orthogonal.

[0123] The extended Latin family sequence generation unit 802 specifically includes:

[0124] The first subunit 8021 is used to copy any column in the N×N...

Abstract

A method for generating Latin square family sequence includes obtaining expansion Latin square family matrix with multiple column expansion Latin square family sequence by carrying out expansion on Latin square family matrix generated according to set prime number and parameter, furthermore realizing frequency hopping communication control on frequency hopping point number being nonprime number according said expansion Latin square family sequence when frequency hopping point number is non-prime number.

Description

technical field [0001] The invention relates to mobile cellular communication technology, in particular to a method and device for generating extended Latin square family sequences, and a frequency hopping communication control method and system. Background technique [0002] With the rapid development of the communication industry, the number of users of the global communication digital mobile phone network grows very rapidly, which requires the expansion of the mobile communication network in time, otherwise it will not only bring great inconvenience to the users, but also affect the business. develop. Because wireless frequency resources are limited, and capacity expansion is not unlimited, how to expand capacity on a large scale under limited frequency resources is a major issue for engineers and technicians. At the same time, with the improvement of users' requirements for mobile communication quality, it is also a problem faced by engineers and technicians to better s...
