Method for inhibiting random access code false alarm

The invention discloses a method for inhibiting random access code false alarm. The method comprises the following steps: measuring a peak value corresponding to the random access code in a target detection window; deducting non-target detection window leakage energy from the peak value to obtain a correction peak value corresponding to the random access code; according to the correction peak value and an absolute threshold, judging whether a user appearing in the target detection window is false alarm; if so, marking in the target detection window. After the embodiment of the invention is applied, the false alarm is effectively inhibited under the condition that the multi-user normal access probability is guaranteed.
