论文摘要
由于其高光谱限制特性和光谱效率，QAM-FBMC被认为是替代CP OFDM的候选波形。 QAM-FBMC在时间和频率上都不可避免地非正交性，并且必须精心设计系统和过滤器以最大程度地减少干扰。但是，现有的QAM-FBMC研究利用匹配的过滤器作为接收器滤波器，不适合非正交系统。因此，在本文中，我们设计了考虑MMSE标准的原型过滤器，并提出了一个在QAM-FBMC中提供最高SINR的系统，该系统无法避免非正交性。此外，我们确认所提出的过滤器在目标SNR上的性能最佳，而不是参考过滤器。
Due to its high spectral confinement characteristics and spectral efficiency, QAM-FBMC is considered a candidate waveform to replace CP-OFDM. QAM-FBMC has inevitable non-orthogonality both in time and frequency, and the system and filter must be well-designed to minimize the interferences. However, existing QAM-FBMC studies utilize a matched filter as the receiver filter, which is not suitable for a non-orthogonal system. Therefore, in this paper, we design the prototype filters considering the MMSE criterion, and propose a system providing the highest SINR in QAM-FBMC which cannot avoid non-orthogonality. In addition, we confirm that the proposed filters show best performance at target SNR than the reference filters.
