Particle swarm clustering ensemble
Extracting natural groups of the unlabeled data is known as clustering. To improve the stability and robustness of the clustering outputs, clustering ensembles have emerged recent...

Joint Precoding for MIMO-Relay Systems with Partial Channel State Information
—In this paper, we propose a joint precoding scheme for both the base station (BS) and relay station (RS) to increase the ergodic capacity of downlink non-regenerative multiple-i...

Power allocation in orthogonal wireless relay networks with partial channel state information
Wireless amplify-and-forward relay networks in which the source communicates with the relays and destination in the first phase and the relays forward signals to the destination in...

Delay-Energy Tradeoffs in Wireless Ad-Hoc Networks with Partial Channel State Information
Given a wireless network where each link undergoes small-scale (Rayleigh) fading, we consider the problem of routing a message from a source node to a target node while minimizing...
