Effect of modulation technique in Mach-Zehnder Modulator (MZM) in optical OFDM system

This paper highlights the bit error rate (BER) performance of a radio-over-fiber system utilizing binary phase shift keying (BPSK), M-QAM, QPSK in the external modulator which is the Mach-Zehnder modulator (MZM). The results have been obtained from the RoF link over 8, 30, 60 90 and 120 km...
