Corporate.Finance.-.Demystified
Corporate finance is the study of the flow of funds into and out of organizations and
the decisions affecting those flows, such as which projects a firm should invest in,
and how they should go about raising the money to do so.
This book is meant to be a plain-spoken introduction to the basic concepts of
corporate finance one, which is suitable for use either as a supplement to a traditional,
introductory college text or as a stand-alone text for students or practitioners who are
interested in a more practical approach to the topic.

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
