signal processing. With XPIC we can have both polarizations running 1024 QAM error free and a net MSE of better than -38 dB with one polarization faded by 18 dB relative to the other on the air (H/V isolation of only 12 dB at the radio input) Hope this answers the question. Chris Gustaf Trango

like 75-80% (or a lower symbol rate if the filtering is not steep enough) and no header compression, which would give them about 250 Mbps for large packets. Hope that helps! Chris Gustaf Trango Systems On Fri, Jan 13, 2017 at 2:39 PM, Mathew Howard <mhoward...@gmail.com> wrote: > W

In general for each increase in modulation level it requires about 3 dB more SNR (see below), and for each doubling of channel bandwidth you lose 3 dB sensitivity. SNR Requirements for Trango and others: QAM/SNR (dB) 256QAM/26.1 512QAM/29 1024QAM/32.5 2048QAM/35.8 4096QAM/40 The frequency
