A consolidated performance investigation and design of newly constructed zero cross correlation resultant weight (ZCCRW) code is presented without mapping over optical wireless channel (OWC) in lower Earth orbit (LEO). Multiple access interference (MAI) is suppressed by incorporating proposed 1‐D code at 10 Gbps with an algorithm. A further state of the art comparison of diverse optical code division multiple access (OCDMA) codes such as multi diagonal codes and diagonal double weight codes is accomplished with proposed code in terms of root mean square (RMS) jitter, extinction ratio, MAI, quality factor (QF), and bit error rate (BER) at different linewidths, chip sizes, link lengths, and active users. It is perceived that for ZCCRW code, QF obtained is 16.5 for chip size (0.1 ns), and at 4000 km, BER 10^‐9 is achieved using the forward error correction (FEC) technique. OWC system in LEO with lasers in spectral amplitude code (SAC) OCDMA is proposed for the first time as per the author's best knowledge.

基于低地球轨道的光学无线信道系统中的零互相关结果加权频谱幅度代码的性能

提出了一种新构建的零互相关结果加权码（ZCCRW）的综合性能调查和设计，无需在低地球轨道（LEO）上的光学无线信道（OWC）上进行映射。通过将10 Gbps的拟议一维代码与一种算法结合在一起，可以抑制多址干扰（MAI）。利用所提出的代码，在均方根（RMS）抖动，消光比，MAI，质量方面，对各种光码分多址（OCDMA）码（例如多对角码和对角双权重码）进行了进一步的现有技术比较因数（QF）和误码率（BER）在不同的线宽，芯片大小，链路长度和活跃用户下显示。可以看出，对于ZCCRW码，码片大小（0.1 ns）的QF为16.5，在4000 km时为BER 10 ^-9使用前向纠错（FEC）技术可以实现。根据作者的最佳知识，首次提出了LEO中的OWC系统以及带有光谱幅度代码（SAC）OCDMA的激光器。
