Abstract :
A reported is presented on the first communication system using vectorial modulation schemes above 500 GHz. Using Schottky-based electronic technologies at 588 GHz, potentialities of high-level multi-carrier modulation schemes for wireless links are analysed. The wireless link is composed of an emitter with a sub-harmonic mixer for up-conversion from 294 to 588 GHz and carrier modulation. A pumped zero-bias detector is used at reception. Mono-carrier signalling is realised using an up to 32-symbol modulation scheme and multi-carrier terahertz transmission is also achieved using several modulation schemes in parallel.
