This report discusses the design and implementation of an OFDM modem for a simplex communication between two PCs over a frequency selective channel. First a brief introduction is provided by explaining the background and the specification of the project. Then the report deals with the system model. Each block of the OFDM system is described (IFFT/FFT, cyclic prefix, modulation/demodulation, channel estimation, bit loading). In the following section, the system architecture is analysed. The transmission protocol, as well as the system parameters is explained in details. Then, the DSP implementation is discussed. Finally, the results are provided in the last chapter.


We would like to thank our project assistant,……….., for his help during the study of this project.
