代码说明：

说明：新一代多普勒天气雷达系统基于对气象和自然灾害的准确预警而产生的。主要应用在于对灾害性天气，特别是与风害相伴随的灾害性天气的监测和预警。它还可以进行较大范围降水的定量估测，获取降水和降水云体的风场结构。(A new generation of Doppler weather radar system is based on the accuracy of weather and natural disasters, early warning generated. Main application is on the severe weather, especially wind damage accompanying the severe weather monitoring and early warning. It can also be a larger range of quantitative estimates of precipitation, precipitation and precipitation cloud body to obtain the wind field structure.)

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 )
