The increasing demand on high bit rate and reliable wireless system has led to many new emerging modulation techniques. One of the techniques will be Orthogonal Frequency Division Multiplexing (OFDM), which is combination of modulation and multiplexing techniques that offers reliable high bit rate wireless system with reasonable complexity. The primary reasons OFDM is preferred in most high bandwidth efficiency transmission systems are because it effectively resist Intersymbol Interference (ISI) and is robust towards fading. This project is found on OFDM research and simulation. After researching OFDM, simulation in MATLAB will be completed. The MATLAB simulation is demonstrates in the form of GUI to show some basic concept of OFDM. To generate the OFDM signals, first, data streams is used as an input to an Inverse Fast Fourier Transform (IFFT), while the output of the IFFT is the sum of the signal samples. The use of Fast Fourier Transform (FFT) algorithms eliminates arrays of sinusoidal generators and coherent demodulation required in parallel data systems. IFFT does the modulation and multiplexing in one step and finally filter out the signal and converts the sample result in baseband signal. Because of its robustness to multipath, and the ease of implementing it in the transmitter and receiver using the FFT, the OFDM concept is growing rapidly in practical importance. 2008-11-14T03:50:30Z 2008-11-14T03:50:30Z 2008-04 Learning Object http://hdl.handle.net/123456789/3253 en Universiti Malaysia Perlis School of Computer and Communication Engineering |
