M-ary Modulation Signalling for Intercellular Communication: an Electrical Engineering Point of View
Résumé
Biologists engineer complex artificial biological systems either to investigate natural phenomena, or to make them perform new tasks such as digital and analog computa- tion, but also intercellular communication. A similarity with computer engineering is often suggested to foster the design of such synthetic biological systems. How- ever, in an electronic communication system, each source generates symbols from a source-alphabet, the size of which may range from 2 (that is two symbols only, 0 and 1) to a few tens of symbols. In practice, for alphabet sizes greater than 2, a binary number composed of bits (0 and 1), or code word, is assigned to each symbol. These code words, or frames, are classically used to transmit information over a digital network. Considering biology, it seems difficult to devise a communication protocol based on the same scheme. In this presentation we will demonstrate that, while an extended-size alphabet is very valuable for intercellular communication, a reference to binary symbols and frames is to be avoided.
