摘要：
In this paper data-aided (DA) frequency domain (FD) channel estimation in a 2x2 multi-input-multi-output (MIMO) system is investigated. Using orthogonal training sequences, fast and robust CD and DGD estimation is demonstrated for a 112 Gbit/s PDM-QPSK system over a wide range of combined linear channel impairments.
