创新性地从多址通信角度讨论正交码的选择问题,借鉴传感网络中能效比的概念,提出用次优正交码代替最优正交码的方案并加以分析,降低了地址码选取难度。随后应用单极性编码有关概念,提出用基于Walsh编码的二维跳频方案为光纤多址技术进行加密的方案,并给出简单示例,为系统融合提供模板,以期在相关领域提供有力背景。
Innovatively discusses the selection of orthogonal codes from the perspective of multi-access communication, draws on the concept of energy efficiency ratio in sensor networks, proposes and analyzes the scheme of substituting the optimal orthogonal codes by suboptimal orthogonal codes, and reduces the selection of address codes Difficulty. Then the concept of unipolar coding is applied. The scheme of using two-dimensional frequency hopping scheme based on Walsh code to encrypt optical fiber multiple access technology is proposed. A simple example is given to provide a template for system integration in order to provide a strong background in related fields.
