“…The resulting photocurrent of PIN is in proportion to the square of the input optical fields (O'Reilly et al 1995). In order to derive the photocurrent of the PIN, the optical carrier is taken as cosine wave and the angular frequency of LD1 and LD2 in Fig.…”

In this paper, a bidirectional radio-over-fiber system based on coherent optical OFDM (CO-OFDM) is proposed. In the downlink, the 60 GHz millimeter-wave (mm-wave) modulated by orthogonal frequency division multiplexing (OFDM) is generated by remote heterodyne detection. The uplink structure is CO-OFDM. Three analyses are applied in OFDM signal processing: pilot frequency inserting, cyclic prefix inserting, symbol synchronization. The "Monte Carlo" simulation method is used to research the system and the simulation result is analyzed by error vector magnitude. The simulation result indicates that the system has a good transmission performance at 40 km coverage span.

“…The second option is to operate the laser in continuous wave (CW) mode and then use an external modulator such as the Mach-Zehnder Modulator (MZM), to modulate the intensity of the light. The two options are shown in Figure 2.7 [25]. In both cases, the modulating signal is the actual RF signal to be distributed.…”

“…The term of interest is Eoi E02 cos [(Q\ -Q2 )t] , which shows that by controlling the difference in frequency between the two optical fields, radio signals of any frequency can be generated. The only limit to the level of frequencies that can be generated by this method is the bandwidth limitation of the photodiode itself [25].…”

First and foremost, I would like to express my most sincere gratitude towards my supervisor Assoc/Prof. A. Alphones. The guidance and inspiration he provided during the course of this project has been invaluable and the project would not have progressed to its current state without his supervision. I would like to take this opportunity to thank Mr. Lim Puay Chye and Ms. Lim Yoke Lan, the technical staff at Communications Lab. IV where this Masters work was carried out. Their assistance was always forthcoming whenever I was faced with any difficulties in acquiring the resources required for this research. Last but not the least, I would like to express my gratitude and appreciation to my friends and colleagues at the Satellite Engineering Centre, for the technical help, encouragement and support they have given me. Particular mention must be made of Mr. Deepak Mohan and Mr. Shantanu Shukla.
