Implementasi non-orthogonal multiple access (NOMA) pada komunikasi cahaya tampak atau visible light communication (VLC) memberikan akses jamak dengan membagi daya sinyal tanpa pemisahan frekuensi ataupun spektrum warna LED pemancar. Dengan konsep umum fair power, alokasi daya perlu dirancang dengan baik agar semua pengakses memiliki probabilitas kesalahan rendah dalam penerimaan sinyal. Penelitian ini memberikan kebaruan secara khusus yaitu model alokasi daya optimal dan adaptif untuk transmisi multi level downlink sistem NOMA VLC. Kontribusi keseluruhan dibagi atas ...

This SpringerBrief introduces the basics of wireless powered communication networks (WPCNs). In particular, the background and concept of WPCNs are briefly discussed. Moreover, this brief provides an extensive study of the recent developments in this area from an optimization perspective. Wireless powered communication network (WPCN) is a new network paradigm for IoT, where wireless devices (WDs) are powered by radio frequency (RF) based wireless power transfer (WPT) to eliminate the need for recharging or ...
