“…where x(i) is the signal after the self-loop interference cancellation in (7). It is shown in [20] that this DLC-STC achieves full cooperative diversity no matter how a delay profile ∆ from the relay is, i.e., it achieves the full asynchronous cooperative diversity, with the maximum-likelihood (ML) or the MMSE-DFE receiver.…”

In this paper, we propose two distributed linear convolutional space-time coding (DLC-STC) schemes for full-duplex (FD) asynchronous cooperative communications. The DLC-STC Scheme 1 is for the case of the complete loop channel cancellation, which achieves the full asynchronous cooperative diversity. The DLC-STC Scheme 2 is for the case of the partial loop channel cancellation and amplifying, where some loop signals are used as the self-coding instead of treated as interference to be directly cancelled. We show this scheme can achieve full asynchronous cooperative diversity. We then evaluate the performance of the two schemes when loop channel information is not accurate and present an amplifying factor control method for the DLC-STC Scheme 2 to improve its performance with inaccurate loop channel information. Simulation results show that the DLC-STC Scheme 1 outperforms the DLC-STC Scheme 2 and the delay diversity scheme if perfect or high quality loop channel information is available at the relay, while the DLC-STC Scheme 2 achieves better performance if the loop channel information is imperfect.

“…In general the term cooperative communication in RADIO is used for approaches where nodes receiving (or overhearing) data don't just convey them to the final receiver but instead they use data in order to enhance communication efficiency. Such approaches have attracted significant interest in more resource rich network technologies such as Wi-MAX [31], [32] but can also benefit RADIO network setups as well. In [33] and [34] a very interesting use of cooperative communication aiming to enhance communication security is offered, which can also be exploited in the context RADIO and extended through the use of state-of-the-art encryption components.…”

Abstract. Demographic and epidemiologic transitions in Europe have brought a new health care paradigm where life expectancy is increasing as well as the need for long-term care. To meet the resulting challenge, European healthcare systems need to take full advantage of new opportunities offered by technical advancements in ICT. The RADIO project explores a novel approach to user acceptance and unobtrusiveness: an integrated smart home/assistant robot system where health monitoring equipment is an obvious and accepted part of the user's daily life. By using the smart home/assistant robot as sensing equipment for health monitoring, we mask the functionality of the sensors rather than the sensors themselves. In this manner, sensors do not need to be discrete and distant or masked and cumbersome to install; they do however need to be perceived as a natural component of the smart home/assistant robot functionalities.
