Problems solved by technology
[0025] The inventors of the present invention have found that if the secondary synchronization code is produced directly according to the definition of the frequency domain secondary synchronization code in the standard, a large number of calculation operations are required, such as finding m 0 and m 1 There are more operations of multiplication, remainder and rounding down in the process, so the consumption of the system is relatively large, and the generation efficiency of the frequency domain secondary synchronization code is low

The invention relates to the field of communications and discloses a frequency domain secondary synchronization code generation method and device. A value range of a cell identification number is divided into N sections (seven sections) according to a specific corresponding relationship among m0, m1 and the cell identification number in advance, the corresponding m0 and m1 can be rapidly obtained according to the specific corresponding relationship among m0, m1 and the cell identification number directly when generation of a frequency domain secondary synchronization code is needed, and a series of operation such as multiplication, complementation and round down in a standard to obtain the needed m0 and m1 does not need. Therefore, arithmetic operation needed by generating the frequency domain secondary synchronization code can be greatly reduced, generation of the frequency domain secondary synchronization code can be achieved through fewer logics in a short time, and generation efficiency of the frequency domain secondary synchronization code can be effectively improved. Preferentially no exclusive or operation is used for replacing the multiplication of an M sequence, the arithmetic operation needed by generating the frequency domain secondary synchronization code is further reduced, and the generation efficiency of the frequency domain secondary synchronization code can be effectively improved.
Description
technical field [0001] The invention relates to the communication field, in particular to the generation technology of the secondary synchronization code. Background technique [0002] In the long-term evolution network (LTE) system, the generation process of the frequency domain secondary synchronization code is as follows: [0003] d L o c a l F r e ( 2 n ) = s 0 ( m 0 ) ( n ) ...
