Description
Technical Field
The present invention relates to the field of data analysis, and in particular, to a system and method for adaptive multiplexing coding.
Background
Data analysis is the basis of a quality management system, and the manager of an organization should evaluate its effectiveness, as appropriate, by analyzing the following questions:
(1) Whether the information for providing the decision is sufficient and credible or not and whether the problem of decision error caused by insufficient information, misalignment and delay exists or not;
(2) Whether the effect of the information on the continuous improvement of the quality management system, the process and the product is consistent with the expected value or not and whether data analysis is effectively applied in the product implementation process or not;
(3) Whether the purpose of collecting data is clear or not, whether the collected data is real and sufficient or not and whether an information channel is smooth or not;
(4) Whether the data analysis method is reasonable or not and whether the risk is controlled within an acceptable range or not;
(5) Whether resources required by data analysis are guaranteed or not.
Meanwhile, the data analysis has a very wide application range, and a typical data analysis may comprise the following three steps:
(1) Exploratory data analysis: when data is just obtained, disorder is possible, no rule can be seen, possible forms of regularity are explored by means of drawing, tabulating, equation fitting in various forms, calculating certain characteristic quantities and the like, namely, the direction and the mode of searching and revealing the regularity hidden in the data;
(2) Model selection and analysis, wherein one or more types of possible models are provided on the basis of exploratory analysis, and then certain models are selected through further analysis;
(3) And (3) inference analysis: inferences are typically made regarding the degree of reliability and accuracy of a determined model or estimate using mathematical statistical methods.
The data analysis may be used for a specific analysis of the channel coded data content. Currently, in signal multiplexing before channel coding is performed, reduction and optimization of the data error rate after multiplexing is performed can be achieved by adjusting the number of multiplexed paths, however, the same multiplexing mechanism has different optimized paths specifically selected due to different data contents to be multiplexed currently, and if a current and simple multiplexing scheme with a fixed path is adopted, it is obvious that the data error rate optimization mechanism is too coarse and solidified.
