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
