Constellation Design for Widely Linear Transceivers [PDF]
EURASIP Journal on Advances in Signal Processing, 2010 Constellation design has been previously addressed by assuming that there is a linear equalizer at the receiver side. However, the widely linear equalizer is well known to outperform the linear one with no significant complexity increase; we derive ...
