An architecture for faster than Nyquist Turbo broadcasting

2012 7th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2012
Recently [16], we have proposed using faster than Nyquist (FTN) signaling to achieve transmission over continuous-time broadcast channels and shown that it can achieve the capacity region of the two-user Gaussian broadcast channel. Benefits of FTN broadcasting include separate encoding and explicit transmission of all users' data, i.e., unlike the ...

Information rates of cyclostationary faster-than-nyquist signaling

2011 12th Canadian Workshop on Information Theory, 2011
Faster than Nyquist (FTN) signaling has been studied as an alternative transmission technology in communication systems when information carrying symbols are sent faster than the Nyquist rate determined by the physical channel bandwidth. This paper presents analysis of the information rates of cyclostationary FTN signaling on AWGN and selected ISI ...

Spectrum Broadening of Faster-Than-Nyquist Signaling Using GTMH Precoding

IEEE Transactions on Aerospace and Electronic Systems
As a promising technique to eliminate the intersymbol interference (ISI) caused by the faster-than-Nyquist (FTN) signaling, the G-to-minus-half (GTMH) precoding could result in severe spectrum broadening and reduce the spectrum efficiency.

Spectrally Efficient Faster-Than-Nyquist Dual-Band Transmission Enabled by Inter-Subcarrier Crosstalk Cancellation

International Conference on Optical Communications and Networks
We propose and experimentally demonstrate an inter-subcarrier crosstalk cancellation algorithm for fasterthan-Nyquist transmission. At 20% HD-FEC threshold, the achievable faster-than-Nyquist rate improves from 0.875 to 0.8 for 16-QAM and from 0.75 to 0 ...
