摘要： Hypothesis tests, such as maximum likelihood detections, are executed on symbol sequences received by, for example, a user equipment (UE) in a communication system. The hypothesis tester checks a received sequence against a group of predetermined sequences that possibly could have been sent to the UE. For received sequences that are matched or not matched by the hypothesis tester with high confidence, complete decoding, for example, with a Viterbi decoder, is not necessary. Instead, complete decoding is used as a “tie-breaker” for those sequences which the hypothesis tester cannot match or not match with desired confidence levels.

摘要： In a robust delay estimator system and method, an average PDP buffer serves as a source of reliable control information to other stages of the delay estimator. The PDP output from every path searcher and tuning finger pass is accumulated in the average PDP buffer, which maintains average PDP estimates for the whole allowable delay spread range. The current (i.e., instantaneous) PDP estimate is then added to the average PDP using an exponential averaging method. The average PDP buffer stores the current PDP estimate and the average PDP estimate, as well as timing and other types of information regarding the estimates. The information in the average PDP provides the necessary information for, and is used to control the operation of, all the individual sub-stages of the delay estimation process.

摘要： In MU-MIMO scenarios, a target mobile terminal can be exposed to data streams intended for other mobile terminals. If the target mobile terminal is capable of interference cancellation, then a serving base station can provide the target mobile terminal with interference information so that the target mobile terminal can efficiently cancel interferences due to these interfering data streams. The interference information includes one or more configuration information, each of which characterizes a related interfering data stream. The serving base station provides the interference information over one or more radio resources that are exclusive allocated to the target mobile terminal or are allocated for common listening. The serving base station exchanges configuration information with neighboring base stations over inter-BS links. The inter-BS links use resources that are different from the radio resources used between the base stations and the mobile terminals.

摘要： Channel estimation and/or equalization processing is performed in a wireless receiver in two stages. The first stage involves pre-filtering in the frequency domain to compact a grid-based representation of the net channel. The second stage involves implementing reduced-complexity time domain channel estimation and/or equalization. According to one embodiment, a received signal transmitted over a net channel is processed by pre-filtering the received signal in the frequency domain. The frequency domain pre-filtering compacts an N-tap effective grid-based representation of the net channel into a K-tap compacted grid-based representation of the net channel where K

摘要： A signal-to-interference estimate is generated using unknown data symbols in place of or in addition to pilot symbols. Data received over a data channel (traffic channel or control channel) are collected. The data symbols are then used to compute an observation metric based on deviations of the data symbols from a predetermined set of possible data symbols, wherein one of the data symbols and symbol constellation is normalized. A data channel signal-to-interference ratio is then computed based on the observation metric.

摘要： Multiple antennas used for data transmission and/or reception are also used to achieve omni-directional antenna functionality. Signals from the antennas are converted to baseband and stored. Phase shifts are applied to the stored signals to steer the effective reception beam in one of a number of directions. A process of interest (e.g., white space sensing) is applied to the beam to produce a result for the given beam direction. By scanning the beam over a number of representative directions, a spatial receiver range equivalent to that of an omni-directional antenna is achieved.

摘要： Methods and apparatus are provided for detecting the radio access technology (RAT) employed in a received signal prior to performing a cell search. The RAT detection method may be used to identify the most likely RAT employed for each candidate frequency identified in an initial frequency scan. Once the most likely RAT is identified, the mobile communication device can then attempt synchronization according to the procedures for the most likely RAT. Identifying the RAT prior to the cell search reduces the number of synchronization attempts and, consequently, the time needed to perform the cell search.

摘要： A target link signal may be received at a receiving device with the target link signal being received in a received signal also including an interfering link signal. A quality of the interfering link signal in the received signal may be estimated at the receiving device to provide an estimated interfering link signal quality. One of a plurality of interference cancellation techniques may be selected responsive to the estimated interfering link signal quality, and an interference cancellation signal may be generated using the selected one of the plurality of interference cancellation techniques. Information of the interference cancellation signal may be incorporated in the received signal. Responsive to incorporating information of the interference cancellation signal in the received signal, the received signal may be demodulated to provide a demodulated target link signal, and the demodulated target link signal may be decoded to provide a target link bit stream.
