Укратко о теми:

The invention of internet has fundamentally changed the underlying information communication infrastructure, and has led to the worldwide telecom boom in the late 1990s and early 2000s. The volume of internet traffic continues to grow rapidly fueled by the emergence of new applications, thus increasing the demand for higher bandwidths. The exponential internet traffic growth projections place enormous transmission rate demand on the underlying information infrastructure at every level, from the core to access networks. The 100 Gb/s Ethernet (100 GbE) standard has been adopted recently (IEEE 802.3ba), and 400 GbE and 1 Tb/s Ethernet (1 TbE) are considered by many authors as next natural steps.

In this talk, we describe four techniques to can enable multi-Tb/s Ethernet, while employing reasonable signal-constellation sizes: subcarrier-multiplexed four-dimensional (4D) coded-modulation, 4D multiband coded-OFDM, generalized-OFDM, and spatial-domain-based coded-modulation.
