Abstract :
We determine the minimum mean-square error (MMSE) performance of a 2-D carrierless AM/PM (CAP) receiver with an ideal (analog feedforward and infinite-length baud-spaced cross-connected) decision feedback equalizer (DFE), in the presence of data-like cross-talks. The MMSE at the slicer is firstly derived for a generic multi-dimensional CAP system with cross-connected DFEs. However, this result requires the explicit factorization of the channel spectral matrix. In the case of the standard 2-D CAP line code, we are able to overcome this difficulty by exploiting the Hilbert transform-pair property of the shaping filters
