Abstract

The present invention relates to the field of network communications, and in particular, disclosed is a multipath fading simulation method, comprising: receiving input signals; according to a calibration control voltage, controlling a power fading amount, and fading the input signals to obtain faded signals; subtracting the power of the faded signals from the power of the input signals to obtain an actual power fading amount; and according to a target power fading amount and the actual power fading amount, determining the calibration control voltage.

Description

technical field [0001] The invention relates to network communication technology, in particular to a multipath fading simulation method and a multipath fading simulation device. Background technique [0002] Microwave equipment belongs to the wireless communication system. During the propagation of microwave signals in atmospheric space, due to the influence of various factors such as atmospheric pressure, temperature, humidity, and propagation terrain, microwave signals reach the receiving end through multiple paths. After vector synthesis, the microwave signal strength is attenuated, resulting in multipath fading. The most intuitive reflection is the rapid fluctuation of RSL (Received Signal Level, received signal level). When multipath fading occurs, the RSL changes rapidly, the duration is short, and occurs frequently within a period of time. Severe multipath fading will cause bit errors or even service interruptions in microwave equipment, seriously affecting normal mi...
