CALL FOR PAPERS IEEE Signal Processing Society Special Issue IEEE SIGNAL PROCESSING MAGAZINE Special Issue on Advanced DSP and Coding for Multi‐Tb/s‐per‐Channel Optical Transport
http://www.signalprocessingsociety.org/uploads/special_issues_deadlines/advanced_dsp.pdf Aims and Scope The exponential growth of Internet traffic places enormous transmission bandwidth demand on the underlying information transport infrastructure at every level, from the core to access networks. In response to the high bandwidth demands, IEEE ratified its 40/100 Gb/s Ethernet Standard IEEE 802.3ba in June 2010. Deployment of 100Gb/s Ethernet (GbE) and its photonic transport layer has already started and is expected to be accelerated within a couple of years. To meet the ever‐growing bandwidth demand, 1Tb/s Ethernet (TbE) systems and multi‐ TbE are to be standardized in the near future. There are several optical transmission technology options, such as DWDM, multibandsuperchannel, and polarization‐division‐multiplexed high‐level QAM, for enabling TbE. However, some challenges still remain with respect to using these techniques as practical technologies for realizing optical TbE. Optical transport in the terabit‐per‐sec‐per‐channel range calls for optimal channel design and requires some extent of parallel processing. The envisioned growth in Internet traffic will place an enormous demand on overall transmission capacity and on the transport infrastructure at all levels. This will also require major improvement in energy efficiency for the processes of bandwidth creation and distribution. As a current example, large data centers are being built closer to power plants in order to facilitate the supply of the energy needed. Recent studies indicate that the power consumed by information and communication technologies, currently at 2‐4% of the total carbon emissions, will have doubled by the end of this decade, assuming that the current trend continues. The Internet is evidently becoming constrained not only by capacity, but also by the energy consumption. It is imperative that the research community addresses both bandwidth and energy constraints sooner rather than later, and any advances, even seemingly incremental ones, will be deemed meaningful. This Special Issue of IEEE Signal Processing Magazine aims to explore novel advanced digital signal processing (DSP) and coding strategies to enable multi‐Tb/s‐per‐channel optical transport for addressing the pressing bandwidth and energy‐efficiency demands. The topics addressed here range from more sophisticated modulation and coding schemes, to advanced detection schemes that are potentially enabling technologies for multi‐TbE optical transport. We welcome contributions on DSP and coding techniques for multi‐Tb/s‐per‐channel optical transport over either single‐mode fibers or few‐mode/few core fibers, as evolution to spatial multiplexing is recently being contemplated for fiber‐optic communications. Proof‐of‐concept of novel DSP and coding techniques through experimental verification will be highly regarded but so will innovative ideas and concepts backed by theoretical proof and simulation.
