摘要

本文讨论了多波段正交频分复用(MB-OFDM)超宽带(UWB)系统的基本结构。采用ECMA 368标准提出的WiMedia联盟的定点仿真平台已经实现。本文还提出了利用Alamouti方法将物理层扩展到多输入多输出(MIMO)系统。基于媒体联盟支持的双载波调制(DCM)理论，提出了一种MB-OFDM MIMO系统的DCM调制和DCM解调软解码方案。采用Saleh-Valenzuela信道模型，分析了系统在室内环境下的误码率和传输范围。

A scheme of Dual Carrier Modulation with Soft-decoding for MB-OFDM MIMO systems

The basic structure of the Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) Ultra-Wide Band (UWB) System is discussed in this paper. The fixed-point simulation platform using the WiMedia Alliance proposed by ECMA 368 standards has been implemented. An extension of the physical layer using the Alamouti method to a Multiple-Input Multiple-Output (MIMO) system is also presented. Based on the theoretical Dual Carrier Modulation (DCM) supported by Media Alliance, we propose a scheme of the DCM-Modulation and DCM-Demodulation with Soft-decoding for a MB-OFDM MIMO system. The system performance is analyzed using the Saleh-Valenzuela channel model in terms of the bits error rate and the transmission range for indoor environments.
