| 摘要: | 软体无线电 (Software Defined Radio) 与正交分频多工 (OFDM) 技术是当今两个重要的通讯发展技术。在本篇论文中，我们首先探讨在不同正交分频多工系统底下的基本数位讯号处理技术，并且分析这些演算法所需要的硬体规格。基于整合通用的数位讯号处理技术以及这些技术个别的需求，我们提出一个适用于多标准的内接收机 (inner receiver) 架构。这个架构整合了四种现今主流的正交分频多工系统，其中包含了数位电视广播系统、数位音响广播系统、无线区域网路系统 (IEEE 802.11a)以及无线都会网路系统 (IEEE 802.16a)。 Software defined radio (SDR) and orthogonal frequency division modulation (OFDM) are two key issues in the technology development of current and future communication systems. In this thesis, we first study basic signal processing techniques for various OFDM-based wireless communication systems and analyze their required computational specifications. Based on the adopted common signal processing techniques and the required specifications, a multi-mode inner receiver architecture is proposed. The proposed receiver integrates various mainstream OFDM-based inner receivers as one, including DVB-T, Eureka147, IEEE 802.11a and IEEE 802.16a. |
