Sentence examples for multiple primary transmitters from inspiring English sources

Cognitive relay networks with multiple primary transceivers under spectrum sharing was considered in [21], where the impact of multiple primary transmitters and receivers on the outage performance of cognitive decode-and-forward relay networks was examined.

In [26], the authors evaluate the outage probability and power allocation for a cognitive network with multiple primary transmitters and primary receivers; the secondary network is composed of a cooperative network with multiple relays, and the direct link at the secondary network is also considered.

Obviously, in the systems with multiple primary transceivers, the interference at SUs from PUs is increasing with the number of primary transmitters, which degrades greatly the performance of cognitive systems.

A robust resource allocation (RA) algorithm for cognitive relay networks with multiple primary users considering joint channel uncertainty and interference uncertainty is proposed to maximize the capacity of the networks subject to the interference threshold limitations of primary users' receivers (PU-RXs) and the total power constraint of secondary user's transmitter and relays.

The proposed scheme is transparent to the primary receivers but inevitably requires some level of modification to the primary transmitters.
