High Performance Faster-than-Nyquist Signaling
In a wireless broadband context, multi-path dispersive channels can severely affect data communication of Mobile Terminals (MTs) uplink. Single Carrier with Frequency-Domain Equalization (SC-FDE) has been proposed to deal with highly dispersive channels for the uplink of broadband wireless systems. However, current systems rely on older assumptions of the Nyquist theorem and assume that a syste...
متن کاملFaster - Than - Nyquist Signaling In a bandwidth
| In this paper, we survey faster-than-Nyquist (FTN) signaling, an extension of ordinary linear modulation in which the usual data bearing pulses are simply sent faster, and consequently are no longer orthogonal. Far from a disadvantage, this innovation can transmit up to twice the bits as ordinary modulation at the same bit energy, spectrum, and error rate. The method is directly applicable to...
متن کاملImproving OFDM: Multistream Faster-than-Nyquist Signaling
Mazo’s concept of Faster Than Nyquist signaling is extended to pulse trains that modulate adjacent subcarriers, in a manner similar to orthogonal frequency division multiplex (OFDM) transmission. Despite pulses that are faster than the Nyquist limit and subcarriers that significantly overlap, the transmission system achieves the isolated pulse error performance. Systems with at least twice the ...
متن کاملIterative intersymbol interference cancellation in vestigial sideband Nyquist–subcarrier modulation system
The intersymbol interference caused by dispersion, chirp, and a vestigial sideband filter in intensity modulation and a direct detection single carrier system is analyzed theoretically and numerically. An iterative nonlinear intersymbol interference cancellation technique is proposed and experimentally demonstrated in a 40Gbps 16-QAMMach-Zehnder modulator-based vestigial sideband intensity modu...
متن کاملOverlap Frequency Domain Equalization for Faster-than-Nyquist Signaling
This letter proposes the Faster-than-Nyquist signaling (FTNS) using overlap frequency domain equalization (FDE), which compensates the inter-symbol interference (ISI) due to band limiting filters of the FTNS at the transmitter and the receiver as well as the frequency selective fading channel. Since overlap FDE does not require any guard interval (GI) at the transmitter such as cyclic prefix (C...
