Control signal detection method with calibration error and subscriber unit therewith

摘要

In a control signal detection method, a calibration error value is obtained by obtaining the mean value of the received continuous (4× n) data, and the calibration error is compensated with respect to the received data by subtracting the obtained calibration error value from the received data, and the correlation value is obtained on the basis of the corrected received data, so that the control signal is detected. Therefore, it is able to compensate the calibration error with ease and to detect the control signal efficiently, with a simple construction.
