In this article, we experimentally demonstrate the amplifier-less transmission of beyond 100-
Gbit/s signal with advanced modulation formats including discrete multi-tone (DMT) and …

The Hilbert transform links the log-magnitude and the phase of the field modulated signals
as long as the minimum phase condition is satisfied in the Kramer-Kronig (KK) receiver. In …

We investigate the parallelized performance of the conventional Kramers-Kronig (KK) and
without the digital up-sampling KK (WDU-KK) receivers in a 112-Gbit/s 16-ary quadrature …

Optical carrier recovery provides a method to increase the carrier-to-signal power ratio at the
receiver side of an optical communications system. Here, we propose to use optical carrier …

We propose and experimentally demonstrate a cost-effective pilot carrier assisted direct
detection scheme based on discrete multitone (DMT) modulation format. The cost of the …

A pilot-assisted direct detection scheme is experimentally demonstrated when distributed
feedback lasers (DFBs) are used as transmitter carrier and pilot carrier sources. In this …

The practical Kramers-Kronig (KK) receiver has been a competitive receiving technique in
the data-center, medium reach, and even long-haul metropolitan networks. Nevertheless, an …

Receiver sensitivity of direct-detection optical orthogonal frequency-division multiplexing
(DDO-OFDM) systems can be significantly improved by using the Kramers-Kronig (KK) …

Kramers-Kronig (KK) receiver shows strong feasibility since the phase can be extracted from
the detected intensity through the Hilbert transform (HT). To reduce the complexity and make …

We experimentally demonstrated the performance analysis of Extended Kalman Filter (EKF)
in a single-polarization 112-Gbit/s 16-QAM transmission over 80/180km standard single …
