Abstract :
Terrestrial point-to-point microwave communication link in tropical region faces excess path attenuation due to rainfall. The rain attenuation causes the receiving signal to fall below threshold level required for specific bit-error-rate (BER) performance. Adaptive power control is design to solve this problem. It increases the transmitting power level according to the signal level arriving in the receiver. This paper describes the design of adaptive power control system and illustrates the operation of the system
