On the characterization of multi-channel applications [PDF]
Proceedings of the 5th international student workshop on Emerging networking experiments and technologies, 2009 We are assisting to the evolution of new generation applications and services, progressively providing - through a single interface - more interactions among the users and between the users and the network. This is promoting the development of multi-channel applications (e.g.

Journal of Telecommunications and Information Technology, 2023 One of the orthogonal frequency division multiplexing (OFDM) system disadvantages is its sensitivity to frequency offset and phase noise, which lead to losing the orthogonality between the subcarriers and thereby degrade the system performance.

In-Tunnel Vehicular Radio Channel Characterization [PDF]
2011 IEEE 73rd Vehicular Technology Conference (VTC Spring), 2011 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.
