摘要： A method and corresponding circuit for determining a final result for a desired series of multiply-and-accumulate (MAC) operations are based on counting the occurrence of products in the desired series of MAC operations, multiplying the counts by their corresponding products to obtain partial sums, and adding the partial sums to obtain the final result. MAC processing as taught herein can be applied to a wide range of applications, such as received signal processing in wireless communication for computationally efficient (and high-rate) generation of interference correlation estimates and/or equalization filter values for a received communication signal.

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.
摘要翻译：在例如通信系统中的用户设备（UE）接收的符号序列上执行诸如最大似然检测的假设检验。假设测试者根据可能已经发送给UE的一组预定序列来检查接收到的序列。对于具有高置信度的假设检验者匹配或不匹配的接收序列，例如使用维特比解码器，完全解码是不必要的。相反，完全解码被用作假设检验者不能匹配或不符合期望置信水平的那些序列的“断路器”。

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： 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： 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.

摘要： A base station herein assists a radio network controller (RNC) to allocate scrambling codes in a cell. The base station's assistance advantageously permits the RNC to allocate different length scrambling codes to different mobile terminals (or downlink carriers) in the cell. Specifically, the base station determines a preference for whether the length of a scrambling code to be allocated to each terminal or carrier should be short or long, based on whether uplink communications transmitted by the terminal, or downlink communications transmitted over the carrier, are to be processed with a high-complexity receiver or a low-complexity receiver. The RNC receives these preferences from the base station and takes them into account in order to allocate either a short scrambling code or a long scrambling code to each terminal or downlink carrier in the cell. The RNC then propagates the scrambling code allocations throughout the cell.

摘要： The automatic frequency correction value applied by a receiver is altered to minimize long-term drift of a path delay profile. In one embodiment, the phase or timing error resulting from constant frequency corrections is accumulated, and an estimated frequency correction value is selectively quantized into an actual frequency correction value in response to the accumulated phase/timing error. The quantized value above or below the estimate is selected to minimize the accumulated phase/timing error that gives rise to path delay profile drift. In another embodiment, a timing circuit measures the instantaneous path delay profile drift incurred with each frequency correction, and integrates the instantaneous drift measurements over time to yield a path delay profile drift. The drift (or its rate of change) is then used to adjust a frequency correction value so as to minimize the drift.

摘要： Methods and apparatus for use in a multiple-input multiple-output (MIMO) system transmitting a plurality of data substreams to a receiver employing ordered successive interference cancellation detection according to a predetermined sequence for decoding the data substreams. A quality of service (QoS) requirement is determined for each of two or more application-specific data streams, and the application-specific data streams are assigned to the data substreams according to the determined QoS requirements and the predetermined sequence, so that application-specific data streams having more stringent QoS requirements are decoded earlier than application-specific data streams having less stringent QoS requirements. In some embodiments, the determined QoS requirements comprise maximum delay requirements, and application-specific data streams requiring shorter maximum delays are assigned to earlier-decoded data substreams than application-specific data streams having less stringent maximum delay requirements. In other embodiments, the determined QoS requirements comprise an application-specific robustness.
