A frequency-diversity microwave system operates at an RF carrier frequency of 7.4 GHz. The IF is a low-index frequency-modulated subcarrier. The baseband signal is a single master group FDM system. The antennas are 2.4-m parabolic dishes. The feeder lengths are 120 mat one station and 80 m at the other station. The reliability objective is 99.995%. The system propagates over an average terrain that has a very dry climate. The distance between stations is 40 km. The minimum carrier-to noise ratio at the receiver input is 28 dB. Determine the system gain.
