  2. Simulation Overview • AWGN and channel models CM1 to CM4 • Bit rates range from 9Mbps to 2.0 Gbps • Fully impaired Monte Carlo Simulation • rake coefficients quantized to 3-bits • 3-bit A to D converter (I and Q channels) • RRC pulse shaping • DFE trained in < 5s in noisy channel (for bitrates >55Mbps) • Front-end filter for Tx/Rx + 6.6 dB Noise Figure • Packet loss due to acquisition failure Michael Mc Laughlin, decaWave

  3. Simulation parameters • Matched filter • 16 rake taps for 110Mbps and greater • Usually 8 rake taps for rates below 110Mbps • Low complexity simulations of 2 rake taps at 9Mbps • k=6 convolutional code (k=4 for ≥ 1Gbps) • Equalizer • 31 Tap DFE for 110Mbps and greater • No DFE used for rates below 110 Mbps Michael Mc Laughlin, decaWave

  10. High Band Performance Michael Mc Laughlin, decaWave

  11. DS-UWB Operating Bands Low Band High Band • Each piconet operates in one of two bands • Low band (below U-NII, 3.1 to 4.9 GHz) – Mandatory • High band (optional, above U-NII, 6.2 to 9.7 GHz) – Optional • Different “personalities”: propagation & bandwidth • Both have ~ 50% fractional bandwidth 3 4 5 6 7 8 9 10 11 3 4 5 6 7 8 9 10 11 GHz GHz Michael Mc Laughlin, decaWave

  12. What high band performance is expected? • Centre frequency is twice as high => lose 6dB. • 2 x Bandwidth => 2 x Total power => gain 3dB • Expect overall loss of 3dB w.r.t. low band in AWGN. • 3dB loss equates to a range factor ~70% • Simulations show AWGN range for 220Mbps is 16.5 m in low band and 11.7 m AWGN in high band. • Although there is a loss of 3dB in AWGN, the loss turns out to be less in Multipath because of the greater frequency diversity and, in some cases, stronger FEC.
