Faster than Nyquist Transmission by Non-Orthogonal Time Division Multiplexing of Nyquist Sinc Sequences. (arXiv:1807.05977v1 [eess.SP])
来源于:arXiv
One possibility to break down the capacity limit in optical transmission
systems are higher spectral efficiencies, enabled by Faster-than-Nyquist
signaling. Here we present the utilization of non-orthogonal time division
multiplexing of sinc pulse sequences for this purpose. The mathematical
expression, with a representation of the Nyquist sinc sequence by a cosine
Fourier series and simulation results show that non-orthogonal time-division
multiplexing increases the transmittable symbol rate by up to 25%. 查看全文>>
