This paper proposes resource-allocation algorithms to maximize the sum-rate in orthogonal frequency-division multiple-access multi-hop relaying downlink systems. With advance subchannel allocation to… Continue Reading
This paper establishes necessary and sufficient conditions for reliable transmission of a source over a relay channel when source side information is available non-causally (a) only at the receiver,… Continue Reading
This paper develops the optimal power-allocation algorithm to maximize the sum-rate in orthogonal frequency-division multiple-access (OFDMA) regenerative relaying downlink systems with separate power… Continue Reading
This paper considers the subchannel-allocation problem to maximize the sum-rate in orthogonal frequency- division multiple-access (OFDMA) regenerative relaying downlink systems with a total power… Continue Reading
This paper develops a optimal power-allocation strategy for the general multi-hop cooperative relay systems. The systems allow a different number of hops for different paths and different… Continue Reading
This paper defines a new metric: a relay gain that measures the performance gain of users using relaying channels at distance s from a base station. The paper derives the closed form of the relay… Continue Reading
