2.8.11.6 XPIC (with MPT-HC V2 only)
The MPT-HC V2 supports Co-channel Dual Polarized (CCDP) operation using a built-in Cross-polarized
Interference Cancellation (XPIC) function (this function is implemented by installing the "RPS+XPIC"
external module). Two links are operated on the same radio channel, with one using the vertical polar-
ization, the other the horizontal. XPIC typically provides 20 dB improvement in polarization discrimination.
The actual improvement will then depend on the native discrimination provided at antenna alignment, and
any reduction of this discrimination caused by atmospheric effects (fading).
XPIC working mode supports modulation scheme 128 QAM and 256 QAM with channel spacing 28 MHz
or 56 MHz.
Adaptive Modulation and ATPC are not supported with the XPIC function.
Radio configuration supported:
– Single 2+0 XPIC
– Double 1+1 HSB co-channel XPIC
