[Industry research] biyesejitognxinxitong DL : 0: 中文摘要正交频分复用（ OFDM ， Orthogonal Frequency Division Multiplexing）是当前一种非常热门的通信技术。它即可以被看作是一种调制技术，也可以被看作是一种复用技术。由于它具有抗多径衰落和频谱利用率高的特点，因此被广泛应用于高速数字通信领域，比如应用于IEEE 802.11a无线局域网（WLAN）的物理层等等。我的毕业设计的核心任务是：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。另外，我还对OFDM技术， IEEE 802.11a的标准文献，基于Simulink 的 OFDM 模型和仿真，ALTERA 公司的技术和 IP Core 的使用等方面进行了研究。这些在文章中都有体现。 -Abstract Orthogonal frequency division multiplexing (OFDM, Orthogonal the Frequency Division, Multiplexing) is a very popular communication technology. It can be seen as a Modulation technique can also be seen as a multiplexing technique. Because of its resistance to multipath fading and spectrum High utilization characteristics, and is widely used in high-speed digital communications, such as used in IEEE 802.11a wireless LAN (WLAN) physical layer. The core mission of my graduation project: FPGA to implement a technology based on OFDM Communication systems in baseband data processing part, ie the modem. These emission part of the modulation Includes: channel coding (Reed-Solomon coding), interleaving, constellation mapping, FFT and interpolation Into the cyclic prefix modules. I also produced a corresponding demodulator can achieve the inverse of the above functions Transformation. In addition, OFDM technology, the IEEE 802.11a standard literature, based on Simulink
