Adaptation of Radio over Fiber Technology Essay

1.1 IntroductionElectronic communication sector is one of the around changing fields in the present world. Mobile communication evaluation happens rapidly within a few(prenominal) years. First generation (1G), second generation (2G) and third generation (3G) are developed within ii decades. Fourth generation (4G) seek is ongoing project. The increasing demand of capacity and coverage leads more look for and development of new technologies to meet with satisfactory performances.See more Is the Importance of being earnest a satirical play essay radio receivercommunication over Fiber technology (RoF) is one of the outcomes of such research with combination of fundamental and featured equipments and communication devices. RoF system of rules are now being used extensively for enhanced cellular coverage both indoor like shopping malls, airport terminal and outdoors. RoF is basically an analog transmission system like other wireless system because it distributes the radio waveform, directly at the radio carrier frequency from a central unit to a Radio Access shoot for (RAP).1.2 ObjectivesObjective of this research is to simulate Radio over Fiber for third generation (3G) die hardard 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, inflexion techniques like BPSK, QPSK and QAM etc are represented with block sets with having its standard parameters. Other parameters like fiber installation, antenna sections, telephone receiver performance kept steady as its normal mode for simulation based 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 forefront to point link. Noise and scattering signal is the main hindrance of establishing a radio link. A huge get of power and a combination 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 inevitable to feed up with a solution for this problem.
