We report on THz communication system using vectorial modulations schemes above 500 GHz. Using schottky-based electronic technologies at 588 GHz, potentialities of high-level multi-carrier modulation schemes for wireless links are analyzed. The wireless link is composed of an emitter with 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 signaling is realized using for up to 32-symbol modulation scheme and multi-carrier THz transmission is also achieved using several modulation schemes in parallel.
