Description: 经典书籍 剑桥大学大学出版社： 无线通信基础-Book Description:
The past decade has seen many advances in physical layer wireless communication theory and their implementation in wireless systems. This textbook takes a unified view of the fundamentals of wireless communication and explains the web of concepts underpinning these advances at a level accessible to an audience with a basic background in probability and digital communication. Topics covered include MIMO (multi-input, multi-output) communication, space-time coding, opportunistic communication, OFDM and CDMA. The concepts are illustrated using many examples from real wireless systems such as GSM, IS-95 (CDMA), IS-856 (1 x EV-DO), Flash OFDM and UWB (ultra-wideband). Particular emphasis is placed on the interplay between concepts and their implementation in real systems. An abundant supply of exercises and figures reinforce the material in the text. This book is intended for use on graduate courses in electrical and computer engineering and will also be of great interes

Description: In this paper, we describe a novel approach for reducing the power consumption and complexity of a multiband orthogonal frequency-division multiplexing (MB-OFDM) ultrawideband (UWB) system by applying ideas from pulsed UWB ystems. The approach is quite general and applicable to many other systems. Unlike the MB-OFDM system, the enhancement that we propose
uses pulses with duty cycles of less than 1 as the amplitude shaping pulse of orthogonal frequency-division multiplexing (OFDM)
modulation.-In this paper, we describe a novel approach for reducing the power consumption and complexity of a multiband orthogonal frequency-division multiplexing (MB-OFDM) ultrawideband (UWB) system by applying ideas from pulsed UWB ystems.

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.

Spatial Multiplexing Systems
Abstract—Multiple-input multiple-output spatial multiplexing
(MIMO-SM) ultrawideband (UWB) systems with orthogonal
frequency division multiplexing (OFDM) signaling are developed.
It is shown that the proposed linear and nonlinear receivers offer
substantial spatial diversity beside data rate enhancement.

Description: 简单地介绍了OFDM-UWB系统，在此基础上用matlab建立了简化的OFDM-UWB基带传输模型。然后分析了同步对系统的影响，可知同步模块是必要的，于是分析了现有的几种同步算法。
结合OFDM-UWB系统的特点，选择了基于同步序列的同步算法，它能同时实现载波和帧同步。然后设计了一种基于S&C算法的联合同步算法，最后用matlab实现了该算法，它能有效地降低BER，并验证了它的有效性。
