摘要

We propose a novel family of optical codes to be used in intra-satellite optical wireless networks. They are Algorithm Optical Codes (AOCs). This family is related with the recently introduced family Random Optical Codes (ROCs). Both families of codes are designed to be used in optical Code-Division Multiple-Access (OCDMA) systems. Similarly than their predecessor, i.e. ROCs, AOCs are specially suitable for optical networks where the number of channels varies, ever large, low bit rate requirements, energy limitations and packed data are presented. For example sensor networks demand these requirements. A detailed description of AOCs is shown in this paper. Furthermore a comparison between them and ROCs is presented. We find that AOCs provide less probability of error than ROCs, for a given length of the code and a number of users. Moreover a system using AOCs can change the length of the code easier than a system using ROCs. This fact permits a more efficient accommodation to the actual number of users. Finally the implementation in an intra-spacecraft Telecommand and Telemeasurement (TC/TM) optical wireless network is also described. We compare the families in the intra-spacecraft optical wireless network.
