Adaptation of Radio over Fiber Technology Essay

1.1 launchElectronic communication sector is one of the most changing field in the present world. Mobile communication evaluation happens rapidly within few years. First genesis (1G), second generation (2G) and third generation (3G) argon developed within two decades. Fourth generation (4G) look is ongoing project. The increasing demand of capacity and coverage leads more seek and development of new technologies to meet with satisfactory movements.See more Is the grandness of world earnest a satirical play essay receiving set over Fiber technology (RoF) is one of the outcomes of such research with conspiracy of fundamental and featured equipments and communication devices. RoF carcass are now being used extensively for enhanced cellular coverage both indoor(prenominal) like shopping malls, airport terminal and outdoors. RoF is fundamentally an analog infection system like other radio set system because it distributes the wireless waveform, now at the piano tuner carrie r frequency from a central social unit to a communicate Access Point (RAP).1.2 ObjectivesObjective of this research is to assume Radio over Fiber for third generation (3G) standard WCDMA system using MATLAB Simulink for microcellular mobile communication system. To achieve this objective various simulink are developed. AWGN channel, Rayleigh channel, Rician channel, optical fiber gain, modulation techniques like BPSK, QPSK and QAM etc are represented with interrupt sets with having its standard parameters. Other parameters like fiber installation, antenna sections, receiver death penalty kept steady as its normal mode for simulation establish study of Radio over Fiber technology.1.3 Background ProblemRadio link of wireless communication suffers from several problems. Atmospheric absorption of radio signal causes a huge distortion in the directional calculate to point link. Noise and scattering signal is the main hindrance of establishing a radio link. A huge amount of power an d a junto of several bulky and expensive equipment is needed to form a radio link. They are vulnerable and not immune to natural calamity. Overall performance is not satisfactory to stand against the increasing global demand of wireless communication. So, a change in network architecture is necessary to deplete up with a solution for this problem.
