Synchronization threshold 1dB (Eb/No) in QPSK, 3,5dB (Eb/No) in 8PSK
Acquisition time 0.25 second
Doppler measurement Yes
Doppler rate 10 kHz/s
IF level measurement accuracy 2 dB
Cable Equalizer (note 1) Yes. Amplitude equalization: 0 to 12 dB between 570 & 870 MHz
Implementation loss 1.6.1.3
Implementation losses:
are given in dB to theoretical value;
take into account all part HDR 4G part the unit filter/demodulator/decoding…;
are given with actual BER measurement using a SDSY Test modulator assuming
no implementation loss @ SDSY test modulator.
<1dB at @ 90% of max value of Bit Rate value
<0,5dB @ 50% of max value of Bit Rate value
<0,3dB @ 25% of max value of Bit Rate value
