Study on QPSK vector signal generation and transmission based on Turbo equalization

Abstract: We propose a novel method to generate photonic quadrature-phase-shift-keying (QPSK) vector signal by using only one Mach-Zehnder modulator (MZM). Because of the ‘square-law’ by the ...

Asymptotic noisy reference losses of subcarrier BPSK and QPSK systems in lognormal fading

Abstract: We study bit-error rate performance of subcarrier binary phase-shift keying (BPSK) and quadrature phase-shift keying (QPSK) systems with carrier phase error ...
