OFDM is one of the applications of a parallel-data-transmission scheme, which reduces the influence of multipath fading and makes complex equalizers unnecessary increase dramatically future wireless communications. OFDM is a particular form of Multi-carrier transmission and is suited for frequency selective channels and high data rates In this project we are going to implement a simulink model design for wireless sensor network standard having OFDM concept. This system will be implemented in simulink toolbox of mat lab and which will have transmitter and receiver with between them standard methodology used for data transmission and at receiver end there will be a analyzer block which will help us to analyze the performance of system on basis of parameters like BER, number of errors etc.
