[0085] The generator polynomial of the Latin square is Equation 1: A α (i,j)=(αi+j)(mod N);

[0086] The generator polynomial of the Latin cube is Equation 2:

[0087] The generator polynomial of the Latin hypercube is Equation 3:

[0088] 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.

[0089] S403. Obtain the el...

Embodiment 2

[0103] like Figure 5 shown, including the following steps:

[0104] S501. Obtain a given prime number N, and generate a scrambled sequence containing N elements;

[0105] S502. Obtain the elements in the scrambled sequence in sequence, and substitute them into the Latin square family generator polynomial as line numbers, respectively, to generate a corresponding scrambled Latin square family square matrix:

[0106] S503. Save the generated scrambled Latin square matrix;

[0107] S504. Obtain the specified column number information, and output the scrambled Latin square sequence of the corresponding column in the scrambled Latin square array.

[0108] The difference between the first embodiment and the second embodiment is that in the first embodiment, only the required scrambled Latin square sequence is generated and output according to the specified column number information. Then, the required scrambled Latin square sequence is retrieved from it as needed.

[0109] Acco...

Embodiment 3

[0111] like Figure 8 As shown, the method for performing frequency hopping communication control according to the scrambled Latin square sequence generated by the method described in Embodiment 1 includes the following steps:

[0112] 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;

[0113] S802, acquiring cell information and user information for frequency hopping communication control, and generating a corresponding Latin square generator polynomial;

[0114] S803, sequentially acquiring the elements in the scrambled sequence, and substituting them into the Latin square generator polynomial as line numbers, respectively, to generate and output the corresponding scrambled Latin square sequence;

[0115] Let the scrambled sequence be V(i), and replace the row number i in the original Latin square sequence with V(i), then:

[0116] 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 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 the ed...
