Inter-relay interference management schemes for wireless multi-user decode-and-forward relay networks
Omri A.; Hasna , Mazen; Letaief K.B. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)In this paper, two cooperative communications schemes with inter-relay interference (IRI) management are proposed for wireless multi-user decode-and-forward (DF) relay networks. The schemes are based on a DF half-duplex ... -
Prior zero forcing for cognitive relaying
Song S.H.; Hasna , Mazen; Letaief K.B. ( IEEE , 2013 , Article)Relaying primary signals by cognitive base-stations (CBSs) can help the primary system and thus win CBSs a higher chance to transmit their own signals. For this purpose, conventional zero-forcing (CZF) beamforming is a ... -
Priority-based zero-forcing in spectrum sharing cognitive systems
Hamdi K.; Hasna , Mazen; Ghrayeb A.; Letaief K.B. ( IEEE , 2013 , Article)We consider a spectrum sharing scenario between cognitive radio (CR) users and a licensed primary user (PU), in which the PU is not able to successfully transmit data to its destined receiver. The cognitive base station ...
