Description: 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

Description: Orthogonal Frequency Division Multiplexing
(OFDM) has been adopted by most wireless and wired communication standards these include wireless Local Area Networks (LANs) HyperLan2, 802.11a, broadband wireless(802.16) and lately the 802.15.3c for millimetre wave communications. In parallel, Field-Programmable Gate Arrays (FPGAs) have become an alternative for the implementation of those standards, due to their increased capabilities (speed and resources). This work introduces the design and performance evaluation of an OFDM transceiver, implemented on a FPGA platform for applications on a wireless millimetre wave radio system, operating around 60GHz.-Orthogonal Frequency Division Multiplexing
