Simulation Overview

• AWGN and channel models CM1 to CM4
• Bit rates range from 9Mbps to 1.32Gbps
• 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 lt 5?s in noisy channel (for
  bitrates gt55Mbps)
• Front-end filter for Tx/Rx 6.6 dB Noise Figure
• Packet loss due to acquisition failure

3
Simulation parameters

• 16 rake taps for 110Mbps and greater
• k6 convolutional code (k4 for 990Mbps)
• Usually 8 rake taps for rates below 110Mbps
• Low complexity simulations of 2 rake taps at
  9Mbps
• 31 Tap DFE for 110Mbps and greater
• No DFE used for rates below 110 Mbps
• 1.9dB Tx power backoff at 9Mbps to allow for
  ripple
