Non-orthogonal Multiple Access Based on SCMA and OFDM/OQAM Techniques in Bidirectional RoF System

Not Accessible

Your library or personal account may give you access

Abstract

Bidirectional RoF system based on SCMA-OFDM/OQAM is proposed to increase spectral efficiency (SE) and support massive users. 1.932Gbps SCMA-OFDM/OQAM signal is transmitted over 24.5km SSMF and 0.3m air distance, resulting in 1.89 times SE increase.
