This paper proposes a method of generating 30 GHz optical millimeter wave (MMW) radio-over-fibre (RoF) by using one dual drive Mach-Zehnder modulator (DD-MZM) which is biased at maximum transmission biasing point to generate optical double sideband suppressed carrier (ODSB-SC) signal. The nonlinear effects of self phase modulation (SPM) in the standard single mode fibre (SSMF) are considered. We compare the performance of optical MMW-RoF system to the wireless radio frequency (RF) signals at 5 GHz with the effect of Rayleigh fading channel. The optical MMW-RoF showed improvements of 40%- 64%when compared to the wireless RF system. At 10 km, BPSK, QPSK and 16-QAM in optical MMW-RoF system showed improvements in power penalty values by 64% and 50%, at 30 km by 50% and 41% and finally at 50 km by 46% and 43% compared to wireless RF system over Rayleigh fading channel, respectively. The optical MMW-RoF system analysis shows that the optimum region falls at 0 dBm optical launch power. At this region the achieved improvements for BPSK, QPSK and 16-QAM optical MMW-RoF are ~64%, ~50%and ~63%respectively.
