Abstract

The invention discloses an FDDLTE base station electromagnetic radiation prediction method, which comprises the following steps: establishing a PDSCH data packet queuing model, considering the arrivalcondition of PDSCH data packets, obtaining parameter values by actually measuring the arrival condition of the PDSCH data packets, solving the average transmission data packet number Navg of a PDSCHby the M/M/m/m queuing model; and calculating the average electromagnetic radiation intensity of the base station in combination with the maximum electromagnetic radiation intensity. The prediction method provided by the invention has great reference value for electromagnetic radiation prediction of the base station, and has certain social benefits.

Description

technical field [0001] The invention relates to a method for predicting electromagnetic radiation of an FDD-LTE base station. Background technique [0002] With the rapid development of mobile communication technology, the demand for communication extends to every corner of people's lives, which brings great convenience to people, but also makes people anxious about the electromagnetic radiation of mobile communication base stations. Among them, the electromagnetic radiation of the base station is closely related to the business data sent by the base station, and the PDSCH channel is the most important physical channel for data transmission in the downlink. However, in the published literature and patents, the PDSCH channel is rarely considered The data packet transmission is related to the electromagnetic radiation exposure of people's body, and the electromagnetic radiation exposure level of the base station is effectively estimated. [0003] Aiming at the deficiencies in...
