This paper studies power distribution in the downlink of a wireless CDMA network, where mobile stations (MSs) cooperatively relay traffic for their peer stations, and the destination station (DS) combines signals received from both the base station (BS) and the relay station (RS). Both the DS and the RSs transmit at the same frequency band. We consider both decode-and-forward (DF) and amplify-and-...
In a cognitive wireless network with spectrum underlay, secondary links can transmit at the same spectrum as primary links as long as the interference to the primary links is below a pre-negotiated interference threshold. This paper studies the effect of setting different interference thresholds on the transmission rate of the secondary links and how secondary transmissions affect the primary links...
