Selection Diversity Combiner Design for Digital LOS Radios

摘要: The use of an offset threshold performance monitor to control selection diversity combining in a digital Line-of-Sight (LOS) radio is explored. A novel hybrid computer simulation used synthesize dual independently fading channels, receivers, monitors and switch. Based on simulations theoretical analysis, design relationships for various switch parameters are defined. optimization these parameters, such as the response bandwidth hysteresis, will maximize improvement obtainable system. Finally, algorithm proposed which integrates outputs from receiver Automatic Gain Control (AGC) assure effective operation under realistic conditions.
