Cooperative communication with single relay selection is a simple but effective
communication scheme for energy-constrained networks. In this paper, we propose a novel …

Future wireless communication systems should be operating mainly, if not completely, on
burst data services carrying multimedia traffic. The need to support high-speed burst traffic …

In this paper, we consider a clustered wireless sensor network where sensors within each
cluster relay data packets to nearby clusters using cooperative communications. We …

We study power allocation for the decode-and-forward cooperative diversity protocol in a
wireless network under the assumption that only mean channel gains are available at the …

We consider a Rayleigh fading wireless relay channel where communication is constrained
by delay and average power limitations. Assuming partial channel state information at the …

User cooperation, whereby multiple users share their antennas and transmit to a common
destination in a collaborative manner, has been shown to be an effective way to achieve …

We are concerned with transmit power optimization in a wireless relay network with various
cooperation protocols. With statistical channel knowledge (in the form of knowledge of the …

In this paper, we consider practical methods to approach the theoretical performance limits
in the fading relay channel under different assumptions of transmitter channel knowledge …

In this paper, we propose a hybrid forwarding scheme for cooperative relaying in orthogonal
frequency division multiplexing (OFDM) based networks. The proposed hybrid forwarding …

This work is devoted to the error rate analysis of underlay multi‐hop cognitive networks with
arbitrary number of hops in the presence of multipath fading. Novel analytic expressions are …
