In this paper, we consider a cognitive relay assisted multiple-input multiple-output (MIMO) communication scenario through Rayleigh fading channel where multiple primary and secondary users wish to communicate with two different receivers in the presence of a cognitive relay. We assume that secondary users transmit simultaneously with the primary users over the same channel instead of waiting for...
In this paper, we study a Multiple-Input Multiple-Output (MIMO) communication scenario through Rayleigh fading cognitive radio channel in which two users, called the primary and the secondary (cognitive) users wish to communicate with two different receivers, subject to the mutual interference. The cognitive user has the causal knowledge of the message being sent by the primary user and is allowed...

We consider a cognitive relay assisted multiple-input multiple-output (MIMO) communication scenario where multiple secondary users wish to communicate with the secondary receiver through Rayleigh fading channels in the presence of a primary user. We assume that secondary users transmits simultaneously with the primary user over the same channel instead of waiting for an idle channel which is traditional...
