The wide spread of low-cost fabrication technologies gives rise to unpredictable imperfections associated with the analog stages which perform the frequency conversion. More specifically, it is well known that such stages suffer from the in-phase (I) and quadrature (Q) imbalance. In this paper, with reference to a single-carrier time-dispersive noisy(More)
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 techniques for constellation design in presence of such an equalizer. The proposed(More)
