Description: This m-file displays the time waveform for the Gaussian pulse function and the first and second derivatives of the Gaussian pulse function for a 0.5 nanosecond pulse width. Other values of pulse widths may be used by changing fs,t,t1. The program uses the actual first and second derivative equations for the Gaussian pulse waveforms. The first derivative is considered to be the monocycle or monopulse as discussed in most papers. The second derivative is the waveform generated from a dipole antenna used in a UWB system. Other information is contained in the file.

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.
