An Uplink Random Access Scheme Based on ALOHA System Assisted by Gain Division Multiple Access
Gain division multiple access (GDMA) is a non-orthogonal multiple access (NOMA) technique for uplink communications. In GDMA, the receiver employs both the magnitudes and phases of channel gains associated to the users to separate users.
