This work aims to analyze the performance of the microwave radio link’s parameters used to connect different systems and intra systems. Fuzzy logic technique is used to study the difficulties of the radio link’s parameters based on type of modulation, and distance between the receiver and transmitter. Four parameters are used as an input parameters for the fuzzy logic system mainly: required power, the length of the microwave radio link, modulation type and the signal to noise ratio(S/N). The output parameter is determined to be the microwave link capacity. Analytical study to select the optimal microwave radio link parameters to examine the efficiency of the radio link capacity will be shown. Additionally, studying the input and output memberships of the microwave radio link parameters using fuzzy logic will be explained.
