Abstract
Due to their greater vulnerability to cross-polarization interference, 64-QAM systems will require a cross-polarization interference canceller (XPIC) for virtually all links. Cancellers of this kind are paving the way to bandwidth efficiencies of up to 10 bit/s/Hz, without requiring 4096 modulation levels. This makes cochannel operation a highly attractive means of achieving maximum bandwidth utilization for digital radio transmission.
