Abstract: In this technical paper A MATLAB SIMULINK MODEL is designed to investigate Pilot Directed Continuous Synchronization of Orthogonal Frequency Division Multiplexing (OFDM) communication systems different mode of channels. This model is valuable for future researchers simulating systems that are too theoretically complex to analyze. The paper details the analysis of a generic OFDM system. An analytical OFDM system using PILOT DIRECTED SYCHRONIZATION OF OFDM WITH DISPERSIVE CHANNEL; FADING CHANNEL AND THEIR COMBINATION WITH AWGN CHANNEL SIMULINK MODEL used to study Delays between transmitted signal and received signal and Bit synchronization from transmitter to receiver. It also counts the various parameters during communication process like Packet Loss; Bit Loss. This technical paper plays a prominent role in the selection of good quality channel with minimum loss of information with high transmission rate for synchronization of transmitter with receiver.
