Performance Comparison Between DF relay and RF Repeaters in the Cellular System
— This paper compares the system level performance of Decode-and Forward (DF) relay and a RF repeater in a cellular system. The results show that for small cell sizes, the repeat...

BER Minimization in Relay-Assisted OFDM Systems by Subcarrier Permutation
—We consider relay-assisted communications from a source to a destination based on OFDM. The relay performs subcarrier permutation by exploiting full channel state information (C...

Clusterization for Robust Geographic Routing in Wireless Sensor Networks
— A cross-layer algorithm for geographic routing in Wireless Sensor Networks (WSNs) is proposed, which is robust to dead-ends and resilient to topological variations due to netwo...

Stochastic Spectrum Pool Reassignment for Cognitive Relay Systems
— We consider a cognitive wireless relay system that operates on secondary spectrum sharing basis using spectrum pooling. A spectrum pool comprises of a set of available narrowba...

Neural Pathways of Embodied Simulation
Simulation theories have in recent years proposed that a cognitive agent's "inner world" can at least partly be constituted by internal emulations or simulations of ...
