Signal Impropriety in Discrete Multi-Tone Systems and Widely Linear Per-Tone Equalization
In the context of digital subscriber line (DSL) systems, where the long-reach (LR) extension of G.fast has recently been proposed, interest in techniques dealing with long channel impulse responses (CIRs) without increasing the cyclic prefix (CP) length of the discrete multi-tone (copyright) modulation has recently resurfaced.The technique under co
