“…This technique permits flexibility and scalability for increased traffic within the aforesaid transmission link. Unfortunately, the developed/reported codes have few limitations as listed: i) Larger Code length [5] ii) Complexity in code design [6] iii) Variable cross correlation [7] iv) MAI [5] v) Less security against eavesdropper and jammer [2] vi) High Cost [8,9]. OCDMA codes with zero cross correlation (ZCC) to eliminate MAI and variable cross correlation are reported in [5], and in [10] code design without mapping for reducing code complexity is presented.…”

Explosive data rate requirements in the satellite communication for surveillance, military services, and broadcasting have put peer pressure on the optical wireless communication (OWC) systems. Secure data transmission against eavesdropper and performance enhancement at authentic user is major concern these days. In this work, performance and security analysis of spectral amplitude codes (SAC) in mode division multiplexed (MDM) OWC have been carried out and a novel zero cross correlation resultant weight (ZCCRW) code at 100 Gbps capacity has been presented. Random diagonal (RD), Enhanced double weight (EDW), Diagonal double weight (DDW) codes have been compared through simulations and also mathematical expressions are derived under the effects of eavesdropper. Hybrid modulations have been compared to check optimal modulation with combination of Laguerre-Gaussian (LG), and HermiteGaussian (HG) modes. Results have revealed that ZCCRW code with MD-DQPSK using LG modes provide best performance and least susceptibility to eavesdropper.
