Method of determining effect of radio wave multipath fading

The invention relates to a wireless charging system request in a method for radio wave multi-path decay average power. System and base station cover of the lower area is coated by a digital map. A lower region in different subdomain to determine transmitter and average power of multi-path decay. In turn to reduce the computational load, determining a through the light tracing method of blocks part of signal parameter decay, and used to the parameter is equal to the subdomain the average power of signal multi-path decay.
