1. 1. Faster than Nyquist Signaling with Spatial Coupling

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Haoran Liu; Lingwei Zhang; [2022]
   Keywords : Technology and Engineering;

   Abstract : The emergence of the Faster-Than-Nyquist signaling (FTN) technology has im- proved the tight spectrum resources by compressing the transmission interval between adjacent pulses. In a natural environment, data transmission via a wire- less medium and through multi-path, at a high data rate, the leakage of these paths among symbols can cause severe inter-symbol interference (ISI).
