"reference signals shifting forward and backward in time (phase noise) lowers multi-level signal modulation performance and data speed... photonic high frequencies signal generator lowers phase noise... set up 6G 300 GHz wireless communication using stimulated Brillouin scattering laser generating signal, also using on-line digital signal processing demodulating signals increasing to single-channel transmission rate 240 Gb /s using on-line DSP... future: multiplexing and more sensitive receivers, data rate 1 Tb /s...
