Blom, K.C.H. (author), Dol, H.S. (author), Berning, F. (author), van Walree, P.A. (author)For underwater acoustic modems to operate in a time-varying environment, in-mission adaptation is desirable. A physical layer has been designed that supports mechanisms for ad-hoc configuration changes based on (in-situ and indirectly obtained) channel and noise conditions. Coded preambles are used to instruct the receiver of a configuration...conference paper 2022

Doost-Mohammady, R. (author), Paweczak, P. (author), Janssen, G.J.M. (author), Segers, J.C.M. (author), TNO Informatie- en Communicatietechnologie (author)In this paper a novel signaling protocol for coexistence and spectrum sharing among cognitive radio nodes is proposed. This protocol allows the radios to rendezvous with each other in a statically allocated spectrum band through on-off keying signaling and reliable spectrum sensing. It enables the radios to have non-cooperative communication in...conference paper 2010

(author), TNO Informatie- en Communicatietechnologie (author)Mobile and wireless communication systems are becoming more and more complex, making understanding the interaction of different technologies on different layers a very difficult task. The introduction of sophisticated techniques on the physical layer that react to changes of the wireless channel on small timescales requires new paradigms for...bookPart 2009

Jorguseski, L. (author), Le, T.M.H. (author), Fledderus, E.R. (author), Prasad, R. (author), TNO Informatie- en Communicatietechnologie (author)The future broadband wireless cellular systems evolved UTRAN (E-UTRAN) and WiMAX are receiving a lot of interest in recent years. Both systems deploy orthogonal frequency division multiplex (OFDM) physical layer consisting of large number of mutually orthogonal sub-carriers. This physical layer provides high robustness against multi-path effects...conference paper 2008

An, X. (author), Zhang, S. (author), Hekmat, R. (author), TNO Informatie- en Communicatietechnologie (author)The IEEE 802.15.3 standard defines a widely-accepted MAC layer protocol for high data rate WPANs. However, resource allocation schemes are not specified in the IEEE 802.15.3 MAC. In this paper, an enhanced IEEE 802.15.3 MAC is proposed for 60 GHz based WPANs. The enhancement relies on a novel resource management scheme. By exploiting the...conference paper 2008
