Fractionally spaced sampling

WebMar 1, 2014 · Fractionally spaced sampling uses two important properties transmitted by digital signals: diversity of the communication channel and the cyclostationarity of the signal. The two properties and the statistical characterization of the data symbols have become the fundamental basis of developing communication channel blind equalization. WebS. F. A. Shah, C. Li, and Z. Zhang, "Low-complexity Fractionally Spaced Equalizer with Non-integer Sub-symbol Sampling for Coherent Optical Receivers," in Advanced Photonics 2015, OSA Technical Digest (online) (Optica Publishing Group, 2015), paper SpT3D.5.

WebSep 26, 2024 · A possible way to overcome this problem is sampling the received signal at rates greater than the nominal one before filtering. This technique is known as fractionally spaced channel equalization , and the resulting filter is the so-called fractionally spaced equalizer (FSE) . WebThe fractionally spaced equalizer (FSE) is an FIR filter and the tap spacing of this filter isT/M, whereM is the over -sampling factor. As the sample period of the input sequence is the same as the tap spacing of the filter, the input sequence to the FSE, r(t), needs Web这 725 个机器学习术语表,太全了!
