Abstract--We propose a cognitive radio system in fading environments where the secondary sender opportunistically violates the secondary-to-primary (S-P) interference power limit. ...
— This paper studies the case where multiple IP flows are aggregated over a single satellite channel and an error recovery by retransmissions is performed by SelectiveRepeat (SR...
The random access systems, with retransmission diversity (RD) employment, over large random spreading code division multiple access (CDMA) channel subject to fading is investigate...
In multiuser communication, the receiver’s performance is degraded by multiuser interference (MUI) as well as multipath distortions. This paper aims at elimination of these side...
The tremendous capacity gains promised by space division multiple access (SDMA) depend critically on the accuracy of the transmit channel state information. In the broadcast chann...
