国外的详细的OFDM设计过程文档，对学习OFDM非常有帮助，并且有仿真结果。-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 backrground 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

are explained in details. Then, the DSP implementation is discussed. Finally, the results are

provided in the last chapter.
