代码说明：

：采用FPGA来实现一个基于OFDM技术的通信系统中的基带数据处理部分，即调制解调器。其中发射部分的调制器包括：信道编码（Reed-Solomon编码），交织，星座映射，FFT和插入循环前缀等模块。我另外制作了相应的解调器，可以实现上述功能的逆变换。-: Using FPGA to implement a technology-based OFDM communication systems in base-band data processing part of the modem. One part of the modulator launch include: channel coding (Reed-Solomon coding), interleaving, constellation mapping, FFT and cyclic prefix insertion modules. I also produced a corresponding demodulator can achieve the above-mentioned inverse transform function.
