Constellation Design for Widely Linear Transceivers

Constellation Design for Widely Linear Transceivers

<p/> <p>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 optimum and suboptimum techniqu...
