Description

[0002] In the Wide Band Code Division Multiple Access (WCDMA) system, the base station determines the coverage of the cell by broadcasting the coverage of the message. Different base stations are distinguished mainly by different downlink scrambling codes. Each cell uses a different scrambling code sequence to scramble the downlink signal.

[0003] The 3rd Generation Partner Project (3GPP TS 25.213) stipulates that the scrambling code sequence is an m sequence composed of two 18-order shift registers X / Y, and then the two m sequences are added together to form a Gold code sequence. The Gold code sequence is a composite code sequence of the m sequence. Every time the relative phase of the two m sequences is changed, a new Gold code sequence will be obtained. The WCDMA system has many downlink scrambling code numbers. The scrambling code number is used as the relative phase difference between the two m sequences to generate different Gold code sequences, and then the two Gold code real sequences are composited into scrambling codes, that is, different downlink scrambling code numbers correspond to different scrambling code sequences.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the WCDMA system, downlink scrambling code is one of the key technologies used to distinguish different base stations. Downlink scrambling code scrambles the data of the downlink channel to ensure that the signals between different base stations do not interfere with each other, and helps the mobile terminal (UE) identify and lock the target base station.

[0029] Each base station uses a unique downlink scrambling code. Mobile terminals identify and distinguish different base stations by detecting the scrambling code. Scrambling can reduce interference between adjacent base stations and improve signal quality. Mobile terminals synchronize with base stations by detecting the downlink scrambling code.

[0030] The downlink scrambling code is generated by two 18-order linear feedback shift registers (LFSRs), which are called X-sequence generator and Y-sequence generator respectively. The initial states of X and Y sequence generators are different. A pseudo-random sequence is generated by a specific polynomial. The X sequence and Y sequence are added modulo 2 (XOR operation) to generate a Gold code sequence. The first 38,400 chips of the generated Gold code sequence are intercepted as the downlink scrambling code.

[0031] Different downlink scrambling code numbers correspond to different scrambling code sequences. The way the WCDMA downlink scrambling code is generated determines that the WCDMA scrambling code sequence has good autocorrelation and cross-correlation characteristics. The X and Y sequence construction method and scrambling code generation process are as follows: (1) Initial conditions: X sequence: X(0) = 1, X(1) = X(2) = … X(16) = X(17) = 0; Y sequence: Y(0) = Y(1) =... = Y(16) = Y(17) = 1; (2) Other values ​​of the X / Y sequence are obtained by the following calculation method: X(i+18) = (X(i+7)+X(i))mod2 Y(i+18) = (Y(i+10)+Y(7)+Y(i+5)+Y(i))mod2 in, .

[0032] (3) The scrambling code sequence Zn is defined as: .

[0033] in, .

[0034] (4) The scrambling code corresponding to the scrambling code number n is calculated as follows: .

[0035] Among them, Sdl,n(i) is the scrambling code corresponding to the scrambling code number n, j represents the imaginary unit, M = 131072, and the sequence can generate a total of There are scrambling codes, of which only 8192 are currently used, with the scrambling code sequence number k = 0,1,…,8191.

[0036] In the current scrambling code generation method, the calculation process of initialization sequence X and Y involves too many cycles, the calculation is time-consuming, and occupies more storage resources.

[0037] Based on the above reasons, the present invention provides a method for generating scrambling codes of a wideband code division multiple access system, which is used to avoid the complex cyclic calculation process in the traditional method, reduce the amount of calculation, improve the calculation efficiency, and reduce the demand for hardware computing resources.

[0038] Figure 1 A flowchart of a method for generating a scrambling code for a wideband code division multiple access system provided by the present invention is shown in FIG. Figure 1 As shown, the method for generating the scrambling code of the wideband code division multiple access system is used in devices such as servers, desktop computers, and notebook computers, and includes the following steps.

[0039] In step 101, a real index value is determined according to a maximum scrambling code number of a downlink scrambling code and a frame length of the downlink scrambling code.

[0040] The downlink scrambling code is a downlink scrambling code in a WCDMA system, and the real index value includes realX and realY.

[0041] In the WCDMA system, the initialization X sequence and Y sequence are known. In addition, the maximum scrambling code number of the downlink scrambling code is 8191. The generation of the downlink scrambling code is only related to the scrambling code number and the scrambling code length. The downlink scrambling code is generated in units of one frame length, that is, the length of the scrambling code generated each time is 38400 chips, that is, the frame length of the downlink scrambling code is 38400.

[0042] Exemplarily, according to the maximum scrambling code number 8191 and the frame length 38400, the index value index is calculated, and the index is used to determine the starting position or offset of the current scrambling code, and realX is calculated and saved according to the following formula; the calculation formula of realX is as follows:

[0043] Among them, index=1: 38400+8192, indicating that the value range of index is 1 to 38400+8192; X is the initialization X sequence in the WCDMA system.

[0044] Exemplarily, according to the frame length 38400, the index value index is calculated, and the index is used to determine the starting position or offset of the current scrambling code, and realY is calculated and saved according to the following formula; The calculation formula of realY is as follows: realY=Y(index) Among them, index=1: 38400 means that the value range of index is 1 to 38400; Y is the initialization Y sequence in the WCDMA system.

[0045] By directly determining the real index value according to the maximum scrambling code number and the frame length, the complex cyclic calculation process in the traditional method is avoided, and the amount of calculation is significantly reduced; in the traditional method, the calculation of the initialization sequence X and Y involves a large number of cycles, while the present method reduces the number of cycles by directly generating the index value, thereby improving the calculation efficiency.

[0046] In step 102, an imaginary index value is determined according to the maximum scrambling code number of the downlink scrambling code, the frame length of the downlink scrambling code and the M value.

[0047] The M value is a constant value in the WCDMA system protocol; the imaginary index value includes imagX and imagY.

[0048] Exemplarily, according to the maximum scrambling code number 8191 and the frame length 38400, the index value index is calculated, and imagX is calculated and saved according to the following formula; the calculation formula of imagX is as follows: imagX=X(index) Among them, index=M+1: 38400+8192+M, indicating that the value range of index is M+1 to 38400+8192+M; M is a constant value in the WCDMA25211 protocol, M=131072; and X is the initialization X sequence in the WCDMA system.

[0049] Exemplarily, according to the frame length 38400, the index value index is calculated, and imagY is calculated and saved according to the following formula; the imaginary index value includes imagY; The calculation formula of imagY is as follows: imagY=Y(index) Among them, index=M+1: M+38400 means that the value range of index is M+1 to M+38400; M is a constant value in the WCDMA25211 protocol, M=131072, and Y is the initialization Y sequence in the WCDMA system.

[0050] By directly determining the imaginary index value according to the maximum scrambling code number and the frame length, the complex cyclic calculation process in the traditional method is avoided, and the amount of calculation is significantly reduced; in the traditional method, the calculation of the initialization sequence X and Y involves a large number of cycles, while the present method reduces the number of cycles by directly generating the index value, thereby improving the calculation efficiency.

[0051] In step 103, a real part of a scrambling code is generated according to the scrambling code number and the real part index value.

[0052] Exemplarily, the calculation formula of the real part of the scrambling code is as follows:

[0053] Among them, realScr is the real part of the scrambling code, xor represents an exclusive OR operation, realX is the real part index value, realY is the real part index value, and n is the scrambling code number.

[0054] By calculating the real part of the scrambling code in real time, the need to pre-store a large number of scrambling code sequences is avoided, thus saving storage space.

[0055] In step 104, the imaginary part of the scrambling code is generated according to the scrambling code number and the imaginary part index value.

[0056] Exemplarily, the calculation formula of the imaginary part of the scrambling code is as follows:

[0057] Among them, imagScr is the imaginary part of the scrambling code, xor represents the exclusive OR operation, imagX is the imaginary part index value, imagY is the imaginary part index value, and n is the scrambling code number.

[0058] By calculating the imaginary part of the scrambling code in real time, the need to pre-store a large number of scrambling code sequences is avoided, thus saving storage space.

[0059] In step 105, a target scrambling code is obtained according to the real part of the scrambling code and the imaginary part of the scrambling code.

[0060] Exemplarily, the target scrambling code is calculated as follows:

[0061] Wherein, scrCode is the target scrambling code; realScr is the real part of the scrambling code; imagScr is the imaginary part of the scrambling code; and i represents the imaginary unit.

[0062] The real and imaginary parts of the scrambling code are calculated in real time, and the target scrambling code is generated as needed, avoiding the need to pre-store a large number of scrambling code sequences and saving storage space; by optimizing the calculation process, the scrambling code can be generated quickly, reducing the system initialization time and improving the system response speed.

[0063] The method for generating a scrambling code for a wideband code division multiple access system provided by the present invention is based on the Gold code sequence generation principle specified in the 3GPP TS 25.213 specification, ensuring that the generated scrambling code meets the standard requirements and is compatible with the existing WCDMA system; since it complies with the 3GPP standard, the method can be directly applied to the existing WCDMA system without large-scale modification of the system.

[0064] The method, device and electronic device for generating a scrambling code of a wideband code division multiple access system provided by the present invention determine a real part index value according to a maximum scrambling code number of a downlink scrambling code and a frame length of the downlink scrambling code, determine an imaginary part index value according to the maximum scrambling code number of the downlink scrambling code, the frame length of the downlink scrambling code and an M value, wherein the M value is a constant value in the WCDMA system protocol, generate a real part of the scrambling code according to the scrambling code number and the real part index value, generate an imaginary part of the scrambling code according to the scrambling code number and the imaginary part index value, and obtain a target scrambling code according to the real part of the scrambling code and the imaginary part of the scrambling code; by directly determining the real part according to the maximum scrambling code number and the frame length The invention provides a method for generating a scrambling code for a wideband code division multiple access system by directly generating an index value, thereby reducing the number of cycles and improving the calculation efficiency; by simplifying the index value calculation and the scrambling code generation process, the demand for hardware computing resources is reduced, and the invention is suitable for being implemented in resource-constrained devices, such as base stations or terminals; the occupation of computing and storage resources is reduced, the system load is reduced, and the stability and reliability of the system are improved.
