Embodiment 1

[0086] As shown in Figure 4, Fig. 4 is the flow chart that the present invention produces disturbance Latin square family sequence, comprises the steps:

[0087] S401. Obtain a given prime number N, and generate a scrambling sequence containing N elements;

[0088] S402. Obtain the set parameter information and specified column number information, and generate a Latin square family generator polynomial corresponding to the given prime number N, parameter information, and specified column number information, wherein:

[0089] The generator polynomial of the Latin square is Equation 1: A α (i,j)=(αi+j)(mod N);

[0090] The generator polynomial for the Latin cube is Equation 2:

[0091] The generator polynomial of the Latin hypercube is Equation 3:

[0092] In the above polynomial, N is a given prime number, α is the set parameter information, i is the row number, j is the column number, 1≤α≤N-1, 0≤i≤N-1, 1≤j≤N- 1.

[0093] S403. Acquire the elements in the disturbed seq...

Embodiment 2

[0107] As shown in Figure 5, it includes the following steps:

[0108] S501. Obtain a given prime number N, and generate a scrambling sequence containing N elements;

[0109] S502. Sequentially acquire the elements in the disturbed sequence, and respectively substitute the row numbers into the Latin square family generator polynomial to generate a corresponding disturbed Latin square family square matrix:

[0110] S503. Save the generated disturbed Latin square matrix;

[0111] S504. Obtain the specified column number information, and output the scrambled Latin square sequence of the corresponding column in the scrambled Latin square matrix.

[0112] The difference between embodiment one and embodiment two is that in embodiment one, according to the specified column number information, only the required disturbing Latin square family sequence is generated and output; in embodiment two, the entire disturbing Latin square family square matrix is ​​first generated and saved, Then...

Embodiment 3

[0115] As shown in FIG. 8, the method for performing frequency hopping communication control by disturbing the Latin square family sequence generated by the method described in Embodiment 1 includes the following steps:

[0116] S801. Obtain the number N of frequency hopping points of the communication system, and generate a scrambling sequence including N elements, where N is a prime number;

[0117] S802. Obtain cell information and user information for performing frequency hopping communication control, and generate a corresponding Latin square family generator polynomial;

[0118] S803. Sequentially acquire the elements in the scrambled sequence, and respectively substitute row numbers into the Latin square family generator polynomial, generate and output the corresponding scrambled Latin square family sequence;

[0119] Let the disturbing sequence be V(i), replace the line number i in the original Latin square sequence with V(i), then:

[0120] The generator polynomial f...

Abstract

The invention relates to mobile beehive communication technology, specially a disturbing latin square group sequence generating method and device and frequency hopping communication control method and system. The disturbing latin square group sequence generating method and device provided in the invention uses disturbing sequence to disturb rule of element in current latin square group, and generate even sequence of bigger element and smaller element, obtain the disturbing latin square group sequence. The frequency hopping communication control method and system uses disturbing latin square group sequence to proceed frequency hopping communication control, within short period, realize even frequency hopping control, and improve effect of frequency diversity.

Description

technical field [0001] The invention relates to mobile cellular communication technology, in particular to a method and device for generating a disturbed Latin square family sequence, and a frequency hopping communication control method and system. Background technique [0002] In wireless communication systems, the spectrum bandwidth used is very limited. With the increase of users and the increase of required rate, it becomes one of the most important issues for the communication system to support multiple users. In order to expand the capacity of the system, the wireless communication system adopts the method of cell system. That is, the area covered by wireless communication is divided into cells one by one, and each cell uses a base station to provide services for the cell. Because the cell is usually hexagonal, the edge is connected with six other cells, and the whole system is shaped like a honeycomb, so it is called a wireless cellular communication system. Since ...
