In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and the specific embodiments of the specification, and it should be understood that the embodiments and specific features of the embodiments of the present invention are detailed descriptions of the technical solutions of the present application, and are not limited to the technical solutions of the present application, and the technical features of the embodiments and examples of the present invention may be combined with each other without conflict.
Example one
Referring to fig. 1, an embodiment of the present invention provides a puncturing method based on a configurable puncturing table, including the following steps:
s1, defining the depth of the initial puncturing table based on the input bit information attribute and the output bit information requirement of various communication protocols; the input bit information attribute comprises an input bit information code rate and an input bit information path number, and the output bit information requirement comprises an output bit information code rate and an output bit information path number;
s2, configuring the initial puncturing table based on the puncturing requirement of the current communication protocol to obtain a task puncturing table matched with the current communication protocol;
s3, based on the task puncturing table, performing puncturing processing on the input bit information of the first code rate to obtain and output bit information of a second code rate; wherein the second code rate is greater than the first code rate.
Further, in the implementation process, referring to fig. 2, the step S2 specifically includes:
s21a, defining a temporary puncturing table corresponding to the input bit information attribute of the current communication protocol in the initial puncturing table; the rows of the temporary puncturing table correspond to the number of input bit information paths, and the columns of the temporary puncturing table correspond to the input bit information code rate;
s22a, based on the puncturing requirement of the current communication protocol, configuring a puncturing indicator symbol in the temporary puncturing table to obtain a task puncturing table matched with the current communication protocol. Specifically, it can be understood that, according to the puncturing requirement of the current communication protocol, a first puncturing indicator symbol or a second puncturing indicator symbol is configured in a cell formed by intersecting rows and columns of the temporary puncturing table; the bit corresponding to the first puncturing indicator in the input bit information of the current communication protocol is a deleting bit, and the input bit corresponding to the second puncturing indicator is a reserved bit.
Further, still referring to fig. 2, the step S3 specifically includes:
s31, periodically reading the information in the task puncturing table to perform puncturing processing on the input bit information of the first code rate to obtain temporary puncturing bit information;
and S32, performing parallel-serial conversion on the temporary punctured bit information to obtain and output bit information of a second code rate.
In the implementation process, the wireless communication systems perform effective communication based on communication protocols, and according to different communication requirements, various wireless communication protocols can be adopted, such as: 802.3, 802.11, 802.16, etc. For each communication protocol, the puncturing requirements defined for the input bit information attributes and the output bit information requirements are different. For example: for a wireless communication protocol, when inputting 2-path 1/2 bit information and needing to output 1-path 3/4 bit information, deleting 1-bit information for each path of input 3-bit information; when inputting 2-path 1/2 bit information and needing to output 1-path 2/3 bit information, deleting 1-bit information when inputting 4-bit information for each path; and so on. The above-mentioned "delete 1-bit information per input 3-bit information" and "delete 1-bit information per input 4-bit information" can be understood as the puncturing requirements respectively corresponding to the conditions "input 2-way 1/2-bit information and requiring output of 1-way 3/4-bit information" and "input 2-way 1/2-bit information and requiring output of 1-way 2/3-bit information". In addition, when the number of input bit information paths and the code rate or the number of output bit information paths and the code rate are changed, the puncturing requirement is also changed correspondingly.
Further, in the scheme of the present application, the input bit information is punctured based on a configurable (or "programmable") puncturing table, so as to improve the bit information transmission rate. It should be noted that, for different communication protocols, there is a corresponding requirement for which redundant bit information bits are punctured when puncturing is performed based on the puncturing table. Please refer to fig. 3, which is a schematic diagram of puncturing according to the wireless communication protocol 802.11g, wherein bit information with a code rate of 2-way 1/2 is input, and bit information with a code rate of 1-way 3/4 is output based on a puncturing table. In fig. 3, a way a (including bits a5 to a0) and a way B (including bits B5 to B0) are input, a puncturing table is shown as T1 in fig. 3, rows of a puncturing table T1 (two rows and three columns, the first row is 0, 1 from left to right, and the second row is 1, 0, 1) correspond to the number of input ways, that is, the first row corresponds to the way a input, the second row corresponds to the way B input, and columns of a puncturing table T1 correspond to input bits of the multiple inputs. The puncturing table T1 is used to puncture 1 bit every 3 bits for each way input. It should be noted that the bit number of the a-way and B-way inputs is 6 bits, which is greater than the column number of the puncturing table T1, and the data in the table T1 can be repeatedly read by the cycle count of the counter to complete the puncturing operation on the input bit information. As shown in FIG. 3, the first reading of the data in table T1 implements puncturing operations for bit data A2-A0, B2-B0, and the second reading of the data in table T1 implements puncturing operations for bit data A5-A3, B5-B3.
Referring to fig. 4, it is a schematic diagram of puncturing that under the wireless communication protocol 802.11g, bit information with a code rate of 1/2 in 2-way is input, and bit information with a code rate of 2/3 in 1-way is output based on a puncturing table. In fig. 4, the correspondence relationship between the input of the C-way and the D-way and the puncturing table T2 is similar to that in fig. 2, since 1 bit is punctured for every 4 bits of each input way, the size of the table T2 is two rows and four columns. As can be seen from fig. 3 and 4, the puncturing table depths are different for different input and output requirements, and the tables T1 and T2 are for the same communication protocol, it should be understood that, in the implementation process, the size of the puncturing table also changes due to the change of the communication protocol, and in order to be able to accommodate different puncturing table size requirements, the depth of the initial puncturing table is first defined, which is large enough to satisfy all predetermined puncturing requirements. The initial erasure table is then configured for a specific communication protocol and communication requirements to obtain task erasure tables (e.g., tables T1 and T2). And then performing puncturing on the input bit information based on the corresponding task puncturing.
Specifically, the task puncturing table may be obtained by configuring, by the controller, the initial puncturing table in the initialization stage. Different input task puncturing tables can obtain different puncturing patterns and further different puncturing code rates. And periodically puncturing the input bits by circularly reading the puncturing table. Still referring to fig. 3, the puncturing indicator in the first row and column of cells in the puncturing table T1 corresponds to input bit a5 or a2, the puncturing indicator in the second row and column of cells in the first row corresponds to input bit a4 or a1, and the puncturing indicator in the third row and column of cells in the second row corresponds to input bit B3 or B0. The a-way and B-way inputs are punctured based on the puncturing table T1, that is, punctured based on the indication of the puncturing indicator corresponding to each bit of the a-way and B-way inputs in the puncturing table T1. For example, in fig. 3, the puncturing table T1 stores 0, 1 data, "0" indicates that the input bit corresponding to the bit of the puncturing table T1 is to be deleted, and "1" indicates that the input bit corresponding to the bit of the puncturing table T1 is to be reserved. In fig. 3, the a-way input data is a 1-A5, the B-way input data is B1-B5, the numerical values of the positions corresponding to A5, B4, a2 and B1 in the erasure table T1 are 0, which indicates that A5, B4, a2 and B1 are erased and not used as outputs, and the remaining data are parallel-serial converted to output OUT1 which is B5, a4, B3, A3, B2, a1, B0 and a 0. The puncturing principle shown in fig. 4 is the same as that shown in fig. 3, and is not described in detail here.
In a specific implementation process, referring to fig. 5, in order to purposefully delete insignificant redundant bits in the input data for different communication protocol types to reduce or avoid the bit error rate, the step S2 specifically includes the steps of:
s21b, judging whether the input bit information is divided into an information bit and a check bit based on the current communication protocol type;
s22, 22b, when the input bit information is divided into information bits and check bits, configuring the initial puncturing table based on the puncturing requirement of the current communication protocol to obtain a task puncturing table matched with the current communication protocol; the task puncturing table is used for performing puncturing processing on the check bits. Specifically, a puncturing indicator for indicating the deletion of the corresponding input bit may be configured in the cell corresponding to the parity bit in the task puncturing table.
In summary, in the solution of the present invention, a puncturing table depth is determined according to an input characteristic and an output requirement of a communication protocol, and a puncturing table is configured based on the puncturing requirement of the current communication protocol, so as to puncture input bit information according to the configured puncturing table, and further obtain required output bit information. The method effectively solves the technical problems that the deletion mode in the prior art is single, can not be changed according to the change of the communication environment and can not realize the compatibility of the deletion modes between different communication systems, realizes the flexibility and the variability of the deletion modes, can not only be compatible with the deletion modes used by the prior communication systems, but also can realize various deletion modes by utilizing the same structure.
