To simulate a OFDM Transmission system using FFT and IFFT for maximum of ten simultaneous users over a AWGN channel with adjustable SNR.The data rates of users shall change randomly with minimum change rate of 1 change per second.
#User Interface: To simulate the entire OFDM system, a Matlab user interface is created. Through the GUI we can
1.Start or stop the simulation.
2.Start and stop user activity.
3.Increase or Decrease the AWGN Channel's SNR value.
4.View the received data for each user.
5.View the transmission statistics like BER,Data Rate for each user
