100G Transport Systems: technology Bench-Mark Testing in China and Evolution to Terabit/s Interfaces

China Communications 2013年第4期10卷 19-30页

作者：张晓宏易小波刘翔 Peter J.Winzer Alcatel-lucent Shanghai bell Alcatel-lucent bell labs

To meet the exponentially growing demand fbr bandwidth in Optical Transport Networks （OTNs）, 100-Gb/s （100G） coherent technology based oil Polarization-Division Multiplexed Quadrature Phase Shift Keying （PDM-QPSK）, which enables the capacity of a Wavelength Division Multiplexing （WDM） system to approach 10 Tb/s, is being widely deployed globally. As the first vendor to intro- duce a single-carrier 100G solution, A1- catel-lucent has developed key transponder and network management technologies, which are reviewed in this paper together with their commercial evolution to 400G. Focusing on the Chinese market, we also review some key bench-mark testing results obtained in partner- ship with major Chinese operators. Finally, we discuss enabling technologies that are currently being researched to allow interfaces to scale to Terabit/s rates.

Differential space-time block-diagonal codes

Science in China(Series F) 2007年第5期50卷 747-759页

作者： LUO ZhenDong LIU YuanAn GAO dinChun School of Telecommunication Engineering Beijing University of Posts and Telecommunications Beijing 100876 China bell labs Research China AlcateI-Lucent Beijing 100080 China Department of Electronic Engineering Tsinghua University Beijing 100084 China

A new differential space-time code, called differential space-time block-diagonal code （DSTBDC）, is proposed for multiple-input multiple-output （MIMO） wireless communication systems. By exploiting the block-diagonal construction of DSTBDC, we can design a variety of high-performance DSTBDC, especially for the cases of large numbers of transmit antennas and high date rates. In flat fading channels, DSTBDC outperforms traditional differential space-time codes if the data rate is higher than 1 bps/Hz, especially when the number of transmit antennas is large. In frequency-selective fading channels, multiple-input multiple-output orthogonal frequency-division multiplexing （MIMO-OFDM） systems using DSTBDC have the powerful ability to achieve very high diversity gain in space, time, and frequency simultaneously. Due to the special orthogonal construction, DSTBDC has a simple decoding algorithm. In addition, DSTBDC can significantly save the cost of radio frequency circuits.
