Frequency-domain equalization supported by training-aided 2× 2 multi-input multi-output
channel estimation (CE) is proposed for coherent optical transmission systems. In particular …

We measure the FM noise power spectral density of quantum-dot mode-locked lasers (QD-
MLLs) and compare this to their measured linewidths as predictors of performance in a …

In future photonic-based THz backhaul links, integrating the optical local oscillator (LO) in a
remote antenna unit can be beneficial in terms of optical bandwidth efficiency and higher …

The performance of long-haul coherent optical fiber transmission system is significantly

As the mobile communication evolves from sub-6 GHz to millimeter wave (MMW) frequency
bands, the demand for high-speed wireless transmission rates exceeding hundreds of …

We investigate, using Monte Carlo simulations, the performance characteristics and limits of
a low-complexity filtered carrier phase estimator (F-CPE) in terms of cycle-slip occurrences …
