Abstract :
Modeling and Simulation can play an important role during all phases of the design and engineering of communication systems. Orthogonal Frequency Division Multiplexing (OFDM) was originally developed from the multi-carrier modulation techniques used in high frequency military radios. In this paper, a simulink based simulation system is implemented using Additive White Gaussian Noise channel (AWGN) to study the performance analysis of Bit Error rate (BER) vs Signal to Noise ratio (SNR). The effect of noise over AWGN channel is observed by using Constellation diagrams and results are concluded by comparing the simulated data with BER Tool.
