A Flexible OFDM System Simulation Model with BER Performance Test

This work aims at developing flexible simulation model for orthogonal frequency division multiplexing (OFDM). In this model, the system parameters such as modulation scheme symbol order, or the number of subcarriers can be changed easily according to specific OFDM system implementation. This system can serve as a key tool for researchers in the area of OFDM systems. In this work, the proposed model is used to conduct different experiments to examine the performance of OFDM system. For instance, the Bit Error Rates (BER) of OFDM system under different noise conditions have been computed. In
