    摘要: A method, system, and device for retransmitting data are provided. The method includes the following steps. In Step A, a receiving device detects a received frame that bears data, determines that the data frame is damaged, and judges whether the number of the damaged frames meets a set retransmission threshold value in a set range or not. If yes, Step B is performed. Otherwise, Step C is performed. In Step B, the receiving device sends a retransmission request to a sending device, the sending device retransmits the frame, and the process turns to Step A. In Step C, the receiving device performs a decoding processing on the data borne in the damaged frame that is received.

    摘要: A wipe sampling assembly used for an ion mobility spectrometer is disclosed. The wipe sampling assembly comprises three layers in which the upper layer and the lower layer are protective paper sheets, while the middle layer is a sampling swab. The swab will not be contaminated when not in use as it is covered by the two protective paper sheets. The hand can only contact the protective paper and will not contact the swab while sampling to prevent the swab from being contaminated. The above wipe sampling assembly is used with no need for any additional device, thus making it easy to operate and carry.

    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.

    摘要: A method and apparatus for creating a bivariate histogram with a plurality of variables using impulse noise data is disclosed. The bivariate histogram describes the joint statistics between at least two of the variables. Also disclosed is an impulse noise monitor (INM) in communication with an impulse noise sensor (INS). The INM receives error data from the INS and creates a bivariate histogram with a plurality of variables using the error data. Included is a method for providing a bivariate histogram with an impulse noise length (IL) and an impulse noise inter-arrival time (IAT) for a plurality of impulse noise events. The IL and the IAT are each measured in integer multiples of discrete multi-tone symbols, and the bivariate histogram is used to determine a minimum impulse noise protection.
