Characterization of multi-channel interference
Multi-channel communication protocols in wireless networks usually assume perfect orthogonality between wireless channels or consider only the use of interference-free channels. The first approach may overestimate the performance whereas the second approach may fail to utilize the spectrum efficiently.

In-Tunnel Vehicular Radio Channel Characterization [PDF]
Inside a tunnel, electromagnetic wave propagation differs strongly from the well understood "open-air" situation. The characterization of the tunnel environment is crucial for deploying vehicular communication systems. In this paper we evaluate vehicle-to-vehicle (V2V) radio channel measurements inside a tunnel.

Characterization of Thermographic Covert Channel
The paper presents a method for determining the characteristics of the information capacity of a thermographic covert communication channel made of a heat radiator (technical black body) and a thermal camera. The determined characteristics are an additional parameter describing these devices in the context of their non-obvious use for data transmission.
