—Hardware platforms and testbeds are an essential tool to evaluate, in realistic scenarios, the performance of wireless communications systems. In this work we present a multiuser Multiple-Input Multiple-Output (MIMO) testbed made up of 6 nodes, each one with 4 antennas, which allows us to evaluate Interference Alignment (IA) techniques in indoor scenarios.(More)
Conformance testing is a crucial activity which aims at stimulating the communication system under test (SUT) to detect errors and unexpected behaviors with regard to the standards. However, when considering distributed systems, the joint and linked stimulation of distributed entities is not easy. The correlation of verdicts obtained from these entities is(More)
This paper describes a sensor based control that releases the user from the continuous attention usually required in opening and closing actions. Further to this local control, the sensory information is used to generate some feedback to the user for the perception of the progress of the hand operation. We are also presented a study and result about the(More)
