Spectrum sharing for two-way relay networks
Abstract
We consider a communication network consisting of two transceiver nodes, one relay node, and one receiving node. The relay enables a two-way communication between the two transceivers and meanwhile sends its own information to the receiving node. We study the problem of the power allocation to the transceiver signal and the relay signal to maximize the data rate of link between the relay node and the receiving node.
Next, we consider a communication network consisting of two transceiver nodes and
two relay nodes. These two relays enable a bidirectional communication between the two
transceivers and meanwhile communicate with each other.
We study the problem of the resource sharing such that the smaller of the data rates of two relays is maximized.
