Design Goals
Burst-by-burst demodulation (no interdependency between the bursts for demodulation)
PRACH
- Time and frequency apertures: ±0.3 ms and ±1.5 kHz.
- Frequency and timing estimation performance:
- Standard deviations of 15 Hz and 6 ?sec estimation accuracy at Es/N0 ? 6.5 dB in AWGN.
- SNR estimation performance:
- Standard deviation less than 0.6 dB for Es/N0 ? 7 dB in AWGN.
PNB
- Frequency and timing apertures: +/- 300 Hz, +/- 85 usec.
- Frequency and timing estimation performance:
- Standard deviations of 10 Hz and 0.3 usec estimation accuracy at
- Es/N0 > 6.5 dB in AWGN.
- SNR estimation performance:
- Standard deviation less than 0.4 dB for Es/N0 ? 4 dB in AWGN.
