Embodiment Construction
[0041] In order to make the purpose, technical solution and specific implementation method of the application clearer, the application will be further described in detail in conjunction with the accompanying drawings.
[0042] This method contains the following prerequisites:
[0043] 1) During the communication process, a pair of aligned orthogonal scrambling codes are used to scramble the physical frames of the two communication parties. For example, scrambling code A and scrambling code B are used, and their quasi-orthogonal characteristics are as follows: Figure 5 shown.
[0044] 2) Define two physical frames of equal length: data frame and training frame, and distinguish them by frame headers. All physical frames with data frame headers are regarded as data frames; all physical frames with training frame headers are regarded as training frames, and all training frames contain the same data.
[0045] 3) The data frame header and the training frame header are quasi-ortho...
