Dynamic spectrum management (DSM) is a new technique for multiuser power allocation and/or detection in digital subscriber line (DSL) networks.
Of all the elements of frequency control available to a Transmission Systems Operator (TSO), by far the most valuable is the availability of an autonomous 5-15 second response window.
We discuss possible architectures and complexity scaling of SDM interfaces that include multiple-input multiple-output digital signal processing (DSP) to deal with coupling between spatial and pola
This is the second part of a tutorial on 1000BASE-T, physical layer of Gigabit Ethernet over copper.
We present a WDM transponder that balances the power between the SD-FEC receiver and the Chromatic Dispersion compensator according to the selected modulation format.
Cellular mobile systems are evolving to offer enhanced packet data services at increased data rates.
In this tutorial paper, we present the application of well-known DSP techniques used in lower speed wireline and wireless applications, to high-speed optical communications.
We demonstrate a novel electronic compensation scheme for demodulator phase error in direct-detection 40-Gb/s DQPSK using a joint digital-signal-processing (DSP).
Digital signal processing has enabled the generation and detection of orthogonalfrequency-division-multiplexing based superchannels that advantageously leverage parallelism to achieve high data-rat
We review the principle and progress of sampled self-coherent optical receiver based on differentialdirect-detection and digital-signal-processing, showing promise of improving receiver sensitivity
