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 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.

摘要： A system for realizing emergency rate reduction (SOS). A receiver initiates a short rate-reduction request, and communicates that request to a transmitter. The transmitter initiates an operational switch to an adjusted transmission reference (i.e., a new bit/gain table), by sending a signal to synchronize the operational switch for both the transmitter and the receiver. The adjusted transmission reference may be calculated using a formula, from a current bit/gain table, or may be a predefined bit/gain table. The parameters of the formula may be predefined, calculated during initialization, or determined in real time during SOS.
