WebJun 8, 2016 · The faster-than-Nyquist (FTN) signalling is a bandwidth-efficient technology which has drawn attention in the bandwidth-starved world. However, inter-symbol interference is introduced by transmitting signals at a higher signalling rate than allowed by the Nyquist criterion. Webing the Nyquist orthogonality criterion. That is by sending the transmit pulse at a rate faster than the Nyquist rate. The history of faster than Nyquist (FTN) signaling started when James Mazo published [3] in 1975. Mazo accelerated sinc pulses beyond the Nyquist rate and found some as-tonishing results. 1.2 Thesis goals

WebDec 8, 2024 · Faster-than-Nyquist (FTN) signaling has attracted interest in the bandwidth-starving wireless systems because it can pack more data in the same bandwidth [ 1 ]. In the FTN signaling, the pulses are sent faster than Nyquist rate, and consequently the pulses are no longer orthogonal.

In signal processing, the Nyquist rate, named after Harry Nyquist, is a value (in units of samples per second or hertz, Hz) equal to twice the highest frequency (bandwidth) of a given function or signal. When the function is digitized at a higher sample rate (see § Critical frequency), the resulting discrete-time sequence is said to be free of the distortion known as aliasing. Conversely, for a given sa… WebThis paper presents an iterative decoder for faster-than-Nyquist (FTN) and orthogonal signaling multi-carrier systems. FTN signaling is a method of improving bandwidth efficiency at the expense of higher processing complexity in the transceiver. The decoder can switch between orthogonal and FTN signaling modes and exploits channel properties to ...

WebWhen the highest frequency ( bandwidth) of a signal is less than the Nyquist frequency of the sampler, the resulting discrete-time sequence is said to be free of the distortion known as aliasing, and the corresponding sample rate is said to be above the Nyquist rate for that particular signal.
