The method and apparatus for measuring distance based on compensation in consideration of change of interference

The distance measurement method of correction based on consideration of a change in the interference and apparatus. Distance measurement method of correction based on consideration of the interference changes in the steps of the distance measuring device transmits a ranging signal to a pedestrian's user equipment via the BLE receives the distance the response signal via the BLE from the user device in response to the ranging signal , the distance measuring device is a pedestrian and BLE distance the primary measurement by a step to the distance measuring device for calculating a primary measurement distance primary measured by the distance between the maximum motion coefficients, before the final decision distance, and based on the distance the response signal calculating a final distance of the pedestrian in consideration of the movement coefficient of the pedestrian with the distance measuring device may include a step of verifying the accuracy of the final distance based on a signal characteristic map generated in consideration of the change in the interference in the space have.
