Multicast in Femtocell Networks: A Successive Interference Cancellation Approach
EAI Endorsed Transactions on Mobile Communications and Applications, 2014 A femtocell is a small cellular base station (BS), typically used for serving approved users within a small coverage. In this paper, we investigate the problem of data multicast in femtocell networks that incorporates superposition coding (SC) and ...
