Description: 多頻帶正交分頻多工之超寬頻系統模擬與等化器設計--超寬頻（Ultra-wideband UWB）是一種已經有實體層規格被提報出來 的新系統，它
具有高位元傳輸率 ，能在短距離 的通訊網路 上提供高速的數 據傳輸。近來 ，因為UWB的
多項優點，使得UWB技術被研究來 用於室內短距離 的傳輸上，且在很多其他的使用上還
有很大的發展潛力 。在這份論 文中，我們將用matlab模擬基於OFDM（Orthogonal
Frequency Division Multiplexing 正交分頻多工）方式的UWB系統基頻部分所有傳送
和接收過程，並設計一個合適的等化器。-Multi-band OFDM Ultra-Wideband System Simulation and Equalizer Design
ABSTRACT :Ultra-Wideband(UWB) is a novel system that has been proposed as a physical layer for a high bit rate, short-range communication network in high performance computing clusters.
Recently, UWB technology is widely studied in many indoor communication systems for its
many advantages, and has a great potential for many other usages. In this report, we are going
to simulate all transmitter and receiver processes of the baseband part of an OFDM-based
UWB system with Matlab, and design an equalizer.

Description: A multi-band orthogonal frequency division multiplexing (OFDM) ultra wideband (UWB) system
is being considered for the IEEE 802.15.3a wireless personal area networks. An enhancement to this system,
named pulsed-OFDM, has been proposed to reduce the complexity and power consumption of the transceiver
without sacrificing performance. In this paper, we describe a detailed implementation of a pulsed-OFDM
transceiver.

Description: 码分多址(CDMA)技术作为第三代移动通信系统的核心技术，具有容量大、抗干扰能力强等优点。然而,传统的CDMA系统属于窄带扩频系统,它的数据速率比较低,不能胜任新一代移动通信系统
（beyond 3G）高速数据通信的需要。而多载波传输技术－正交频分复用（OFDM），作为后三代移动通信的核心技术，则具有高数据速率传输的特点。-Code Division Multiple Access (CDMA) technology as the third generation mobile communication system' s core technology, high capacity, anti-interference ability and so on. However, the traditional narrow-band CDMA system is spread spectrum system, and its relatively low data rate, can not do next-generation mobile communication systems (beyond 3G) high speed data communication needs. The multi-carrier transmission technology- orthogonal frequency division multiplexing (OFDM), after three generations of mobile communications as a core technology, the high data rate transmission characteristics.
