摘要
PURPOSE: An RF system calibration algorithm by predicting nonlinear features is provided to segment an output level of a system, and to estimate output features in each section to determine an input level in accordance with an output, thereby tremendously reducing a compensation time at high precision. CONSTITUTION: An input signal and an output signal of a wired/wireless terminal are measured by a measurer, and a compensation value is calculated by using an operator/controller. The operator/controller transmits an operation control signal in accordance with the compensation value to the wired/wireless terminal, in order to compensate for an error of the input/output signals. An input/output range of the wired/wireless terminal is segmented in plural ranges, so as to enable linearization in each section. An input level in accordance with a desired output level is calculated.
