Fiber-optic research in signal processing for the first generation of coherent communication
systems was dominated by receivers with blind adaptation. Next-generation systems will …

A method of suppressing effects of aliasing in a system for digitally processing a high speed
signal having a symbol rate of 1/T. The high speed signal is sampled at a fractional multiple …

Optical access networks may be employed to deliver a wide variety of services, such as fiber
to the home (FTTH), fiber to the building (FTTB), enterprise connectivity, business …

BACKGROUND For the purposes of understanding the present disclosure, it is useful to
consider a representation of the total optical E-field E (t) as a vector confined to a plane and …

An optical transceiver converts a received optical signal to an electric signal and converts
the electric signal to a digital signal, and has an adaptive equalizer to adaptively equalize …

A system for high fidelity analog RF photonic communications is disclosed wherein linear
phase modulation and linear coherent demodulation is included. A single optical beam with …

US PATENT DOCUMENTS is oversampled to generate a multi-bit sample stream. The
sample stream is partitioned into blocks of contiguous samples, wherein each block of …

In some optical communication systems, a coherent optical receiver has a local optical
oscillator that is not phase locked to the received data-carrying optical carrier. In Such …

In one embodiment, a receiver of the invention has an optical detector coupled to a digital
processor. The optical detector is adapted to mix the received optical quadrature-amplitude …

A signal equalizer for compensating impairments of an optical signal received through a link
of a high speed optical communications network. At least one set of compensation vectors …
