摘要：
In this paper we explore the possibility of using Energy-Division Multiple Access (EDMA) scheme for uplink communications in a cognitive radio context in order to allow transmission to unlicensed users overlapping with the primary user in both time and frequency domains. The proposed solution is energy consuming for unlicensed users, thus represents a viable solution when spectral efficiency and/or latency are more crucial than energy constraints. Simulation results in scenarios with Orthogonal Frequency Division Multiplexing (OFDM) transmissions, both uncoded and coded cases, are presented.
