摘要： Bit probability estimates generated by a turbo decoder are employed to weight the bits of a received packet before combining the received packet with a redundant packet. Bits are individually weighted by the corresponding bit probability estimate and all bits within the received packet are weighted by a block confidence estimate generated from the cumulative bit probability estimates for the received packet. Weighted packet bits are combined within either weighted packet bits for the redundant packet or unweighted received bits for the redundant packet. The bits are combined by adding counterpart weighted (or weighted and unweighted) systematic and parity bit values within the two packets while inserting disjoint parity bit values within the combined result. Decoding performance for incremental redundancy systems utilizing turbo decoding is improved.

摘要： A system, method and computer program product are provided. The system includes a demapping element, and may also include a master controller. The demapping element is capable of estimating an amplitude of a signal constellation of a QAM signal. In this regard, the signal includes a pilot channel and a supplemental channel, where the supplemental channel includes traffic of a user and at least one other user. The demapping element is capable of estimating the amplitude based upon a power of a signal combination of a traffic symbol and a pilot symbol. The system can also include a master controller in electrical communication with the demapping element. The master controller can then be capable of demodulating the traffic of the user in the supplemental channel of the QAM signal based upon the estimate of the amplitude.

摘要： Apparatus, and an associated method, for effectuating power control in a radio communication system, such as an IS-95/IS-2000 system which deploys 1×EV-DO technology. At a mobile station, a channel indicia measurer measures channel conditions upon a radio link. Responsive thereto, a data rate selector selects a data rate at which subsequent data is to be communicated to the mobile station. The selection is returned to the network part of the communication system. A selector selects the power level at which to communicate the subsequent data to the mobile station responsive to the requested data rate. The requested data rate is used as a metric by which to select the power level at which to communicate the subsequent data to the mobile station.

摘要： A system, method and computer program product are provided for demodulating Quadrature Amplitude Modulated (QAM) signals based upon a speed of a receiver. The system includes a receiver and a demapping element. The receiver is capable of receiving a QAM signal over at least one slot. The demapping element can then be capable of estimating the amplitude of a signal constellation of the QAM signal over either one or more of the slot(s) or fractions of the slot(s) based upon the speed of the receiver. More particularly, the demapping element can estimate the amplitude by first estimating an expectation of a power of a signal combination of a traffic symbol and a pilot symbol, where the expectation can be estimated over either one or more of the slot(s) or fractions of the slot(s). The demapping element can also estimate a bias, and thereafter estimate the amplitude based upon the expectation of the power of the signal combination and the bias.

摘要： For example, a wireless communication device may be configured to generate, transmit, receive and/or process one or more transmissions of an Extra Range (ER) Physical layer (PHY) Protocol Data Unit (PPDU), which may be configured to be decodable by ER wireless communication stations (STAs). For example, the ER PPDU may include an ER preamble. For example, the ER preamble may be configured to include an ER STF (ER-STF), an ER LTF (ER-LTF) after the ER-STF, and an ER Signal (ER-SIG) field after the ER-LTF. In one example, the ER PPDU may include a non-ER preamble, which may be configured to be decodable by non-ER STAs, which may not be capable of decoding the ER preamble.
