商品描述

Multicarrier communication methods such as Orthogonal Frequency Division Multiplexing (OFDM) and Filter Bank Multicarrier (FBMC) permit the implementation of dynamic spectrum access thanks to their ability to finely control signal transmission over specific frequency subbands. Therefore, multicarrier methods are strong candidates for the physical layer of spectrum sharing applications and cognitive radios. This dissertation explores methods for spectrum awareness and opportunistic access of multicarrier radios based on the allocation of subcarriers in blank spectral spaces. Following a theoretical description, a physical layer hardware design based on FPGA is presented, including the description of a working prototype with solutions to the tasks of spectrum sensing, frame detection, synchronization, channel estimation, demodulation, and mutual interference mitigation.

商品描述(中文翻譯)

多載波通訊方法,如正交頻率分割多工(OFDM)和濾波器組多載波(FBMC),通過精確控制信號在特定頻率子帶上的傳輸,實現了動態頻譜訪問的能力。因此,多載波方法是頻譜共享應用和認知無線電物理層的有力候選者。

本論文探討了基於在空白頻譜空間中分配子載波的多載波無線電的頻譜感知和機會訪問方法。在理論描述之後,提出了一種基於FPGA的物理層硬體設計,包括一個工作原型的描述,並提供了頻譜感知、幀檢測、同步、通道估計、解調和互干擾抑制的解決方案。
