In this paper, an integrated 16×10 Gbps mode-division-multiplexing and optical-code-division-multiple access (MDMOCDMA) technique based inter-satellite optical wireless communication (IsOWC) model is presented. To enhance the system security and capacity, different orbital angular momentum (OAM) beams and distinct improved zero crosscorrelation code sequences are transmitted. The results exhibit that the proposed model offers 36,000 km range with 8.10e8 watt signal power. The system can sustains spot size of 15 µm and offers massive capacity at 25 cm aperture diameter. Moreover, the system offers better performance than existing codes supporting 128 end-users at 0.5-5 dB additional loss with 15 µrad divergence angle providing 95.94 dB gain and 21.45 dB signal-to-noise-ratio.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
