This paper investigates a cooperative transmission scheme for a multi-source single-destination system through signal-superposition-based braid coding. The source nodes take turns to transmit, and each time, a source “overlays” its new data together with (some or all of) what it overhears from its partner(s) using signal superposition, in a way similar to French-braiding the hair. We demonstrate how...
We propose a forwarding scheme by superposition coding for wireless relaying, in which a relay will not forward a message to a destination if the destination has successfully decoded the message directly from a source. In our scheme, flag signal and data signal are superimposed and transmitted by the source, and according to whether the flag signal has been successfully decoded by the relay, the relay...
Advances in micro-nano-biosensor fabrication are enabling the integration of a large number of biological recognition elements within a single package. As a result, hundreds to millions of tests can be performed simultaneously and can facilitate rapid detection of multiple pathogens in a given sample. However, it is an open question as to how to exploit the high-dimensional nature of the multi-pathogen...
