摘要: A device and a method for clipping multicarrier signal are provided. The method for clipping multicarrier signal includes: detecting whether an Idle Period in DownLink (IPDL) starts in each subcarrier forming a multicarrier joint signal and generating an IPDL flag just when the IPDL starts in a subcarrier; detecting power of each subcarrier to get a detection result; selecting a clipping filter coefficient according to the IPDL flag and the detection result; performing a clipping processing of the received multicarrier joint signal according to the clipping filter coefficient and outputting the multicarrier joint signal after the clipping processing. Embodiments of the present invention meet demands of an IPDL time template and effectively support an IPDL mechanism in a Wideband Code Division Multiple Access (WCDMA) system on the premise of no multicarrier signal clipping performance is affected.
