摘要

采用不同的算法和用户在基本代码矩阵上的固定值构造双权码族。提出了一种DW码族的单码构造算法，其中基本码矩阵的用户数量取决于码权值和一个常数。映射用于提供更多的用户数量。分析了基本矩阵(用于映射)对误码率和码长的影响。本文提出的编码构造算法具有易于编码构造的特点，采用任意正整数值的权值进行编码构造，通过不同大小的基本矩阵设计不同的编码集。接收机平衡检测技术采用前或函数。利用MATLAB对数值结果进行了计算。

A new code construction algorithm based on Double Weight codes for SAC-OCDMA systems

Double Weight (DW) code families are constructed with different algorithms and fixed value of users at basic code matrix. A single code construction algorithm is proposed for DW code families in which, number of users for basic code matrix depends on the code weight and on a constant value. Mapping is used to provide the greater number of users. Affect of basic matrix (used in mapping) on Bit Error Rate (BER) and code length is analyzed. The properties of proposed code construction algorithm are easy code construction, any positive integer value of weight is used for code construction, design of different code set by varying size of basic matrix. Ex-OR function is used in balanced detection technique at receiver. Numerical results are calculated using MATLAB.
