| 摘 要： | 以哈达玛(Hadamard)矩阵为基础,给出一种二维空间相位码的编码方法,分析它的各种性能,并用这种二维空间相位码作为用户的地址码,构成一种新的空间-相位码分多址系统,使光码分多址编解码在空频域内进行,由于对空频域内的信息只作相位调制,大大提高了光传递效率。

| Abstract: | An encoding method of two-dimensional spatial-phase code is given on the basis of Hadamard matrix, its performance is analyzed. A new spatial-pha se code-division multiple access system is constructed by means of two-di-mensio nal spatial-phase code matrix. Encoding/decoding of optical code-division multip le access will be implemented in spatial-frequency domain. For phase-only modul ation in spatial-frequency domain, the optical transmission efficiency of the s ystem is highly enhanced. |
