Abstract

A fast frequency hopping post detection integrator (FFH-PDI) system that uses path diversity combination techniques is proposed. The delay spread present in multipath fading channels can be used to improve communication performance. This is possible because the delayed paths are resolved and path diversity combination is realized. The use of this method is advantageous in combatting interference, as the system adds the desired components and averages the interference components. The usefulness is confirmed by computer simulations
