M-PSK versatile modulation using a single-electrode straight-line phase modulator and digital signal processing for ISI-suppression

BPSK, QPSK, and 8-PSK modulation/demodulation was experimentally demonstrated using only a single-electrode straight-line phase modulator for the first time. ISI caused by the modulation was compensated by pre-equalization based on digital signal processing, achieving BER<10-
