PROBLEM TO BE SOLVED: To provide a temperature correction method and a temperature correction device for a received signal strength indicator.SOLUTION: A temperature correction device includes: a temperature sensor that measures a current temperature; and a digital correction module that, on the basis of the current temperature, selects a temperature correction coefficient from temperature correction coefficients corresponding to an atmospheric temperature, a low temperature and a high temperature which are preliminarily stored, performs a temperature correction to an output signal of a received signal strength indicator (RSSI) on the basis of the selected temperature correction coefficient, and acquires an electric power of an input signal of the RSSI. The method and the device according to the present invention measure characteristics of three temperatures of the RSSI, correct temperature characteristics of the RSSI by an interpolation method and thereby acquire an accurate electric power value of the input signal at any temperature. In comparison with a conventional art, the method and the device according to an embodiment of the present invention reduce a usage volume of a memory and improve accuracy of the temperature correction. |
