摘要

本文提出了用单重合跳频码(OCFHC)进行波长分配，用同余码(CCs)进行时隙分配的二维新码的构造方法。在大气湍流和各种天气条件下，对OCFHC/二次同余码(OCFHC/QCC)进行了性能评价。对弱湍流采用对数正态模型，对中、强湍流采用伽马-伽马模型。各种天气条件，如浓雾，轻雾和非常晴朗的空气在评估中被考虑。

Performance analysis of wireless OCDMA multi-user system based on new 2-D code in presence of atmospheric turbulence and various weather conditions

In this paper, we propose construction method of new two-dimensional (2-D) codes where one-coincidence frequency hopping code (OCFHC) is used for wavelength assignment and congruence codes (CCs) for time slot assignment. The performance evaluation of the OCFHC/quadratic congruence code (OCFHC/QCC) is made in presence of atmospheric turbulence and various weather conditions. Lognormal model is used for weak turbulence and gamma-gamma model for moderate and strong turbulence conditions. Various weather conditions like thick fog, light fog and very clear air are considered in the evaluation.
