Method of Throughput Calculation for Microwave Link with Adaptive Modulation Under the Fading Conditions Inherent for Millimeter Waves

Abstract

The article is devoted to the development of a method for calculating the capacity of microwave links with adaptive modulation under fading conditions in millimeter wave range. The relationship between throughput and unavailability coefficient of microwave links with different transmission rate levels are is shown for a known distribution function of fading. The results of data analysis of fading statistics at microwave links in the E-band range (71–76/81–86 GHz) and meteorological statistics are presented. The relationship of both statistics was revealed and taken into account in the proposed analytical equation for the distribution function of fading. A comparative analysis of the calculation results of the unavailability coefficient and throughput at microwave links in the E-band range was carried out based on the proposed distribution function as well as based on the distribution functions of existing methods. High relevance of the developed method to the measurement results is shown.
