In the digital communications, due to the timing-offset existing between the transmitter and receiver, timing synchronisation is a critical problem which may have dramatic effect on the transmission performance in the faster-than-Nyquist (FTN) signalling system. For solving this problem, considering the intentionally intersymbol interference introduced by FTN, a new non-data aided timing-delay estimation...
Considering the intentionally introduced inter-symbol interference and coloured noise, proposed is a new signal-to-noise ratio (SNR) estimator based on the expectation-maximisation algorithm for the faster-than-Nyquist signalling system. The proposed SNR estimator can maximise the likelihood function by iteratively using the soft information from the channel decoder. Moreover, the new SNR estimator...
