Microwave Radio Frequency Optimization and Link Performance

This paper presents an optimization methodology for fixed service microwave link. To obtain high throughput on the microwave link, the possibility to use wideband channel and low modulation or the reverse are possible. We present a methodology to obtain high speed and best performance for microwave links based on modulation and frequency channel choice. In the first time we present a microwave design parameters, the performances of an Additive White Gaussian Noise channel (AWGN) and we propose a methodology for the ITU-RF adjacent channels arrangement optimization to obtain a high speed transmission with a best fade margin (99.9998% of annual availability). In the second time, we present an experimental design using a microwave link design tool and measurements on physical link.
