Slide Show on Diversity Reception

Pure selection diversity

• Select only the strongest signal
• In practice: select the highest signal + interference + noise power
• Use delay and hysteresis to avoid excessive switching
• Simple implementations: Threshold Diversity
  • - Switch when current power drops below a threshold.
  • - This avoids the necessity of separate receivers for each diversity branch.

Probability of fade versus fade margin in dB. Various degrees of selection diversity
