Embodiment Construction
[0038] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0039] figure 1 It is a flow chart of the construction method of the optical orthogonal code whose autocorrelation constraint is 2 in the present invention, such as figure 1 Shown:
[0040] The construction method of the optical orthogonal code whose autocorrelation constraint is 2 of the present invention comprises the following steps:
[0041] S1. According to the number of code words n and the code weight w required to be constructed, an integer array M is constructed;
[0042] S2. Fetching numbers from the integer sequence M according to the preset number fetching rules, constructing a triangular matrix D of signal difference distances and a set T of difference distance pairs of optical orthogonal code codewords w...
