摘要： In a multi-radio device, a configurable filter may be placed on the transmit side of an aggressor radio to reduce interference to receive side performance of a victim radio. The filter may be adaptively configured based on performance of the victim radio. The configurable filter may be in the form of a notch filter. The depth and width of the notch filter may be configured. The filter may be used to create a virtual guard band between an Industrial Scientific and Medical (ISM) band and a cellular band by puncturing a physical uplink control channel (PUCCH) transmission nearest to the ISM band or reducing power on the nearest PUCCH transmission.

摘要： Techniques for performing interference cancellation in a wireless (eg, CDMA) communication system are described. For a single-sector interference canceller, received samples are processed (e.g., despread) to isolate a signal from a transmitter (e.g., a base station) and obtain input samples. The input samples are transformed based on a first transform (e.g., a fast Hadamard transform) (416) to obtain received symbols for multiple orthogonal channels (e.g., Walsh bins) . The received symbols for the multiple orthogonal channels are scaled with multiple gains (440) to obtain scaled symbols. The gains may be related to the inverses of the power estimates for the orthogonal channels. The scaled symbols are transformed based on a second transform (e.g., an inverse fast Hadamard transform) (442) to obtain output samples, which are processed (e.g., spread) to obtain interference-canceled samples having the signal from the transmitter suppressed.

摘要： Techniques for performing interference cancellation in a wireless (e.g., CDMA) communication system are described. In one aspect, per-bin power estimates for multiple orthogonal bins are derived by estimating at least two components of these power estimates. The components may include, e.g., channel gain, noise and interference, and bin gain. Interference cancellation is performed based on the per-bin power estimates. In another aspect, interference cancellation is performed in multiple stages with fast tracking. A total power estimate and per-bin power estimates are derived for a first stage. A total power estimate is derived for a second stage. Per-bin power estimates are also derived for the second stage based on the total power estimates for the first and second stages and the per-bin power estimates for the first stage. Interference cancellation is performed for each stage based on the per-bin power estimates for that stage.

摘要： Receiver diversity in a wireless device is controlled in response to operating conditions, transmission requirements, and control settings. The control of diversity reduces power consumption by enabling receive diversity on given conditions. Operating conditions, transmission requirements, and control settings are used separately or used in conjunction to determine whether benefits of multi-antenna receive diversity, such as higher link capacity, higher data throughput, lower transmit power, and lower error rate, warrant the higher power cost of the diversity.

摘要： A method for estimating a traffic-to-pilot ratio (TPR) for a received signal is disclosed. The received signal is despatialized to obtain a despatialized received signal. A channel matrix is despatialized to obtain a despatialized channel matrix. The despatialized received signal is whitened to obtain a pre-whitened despatialized received signal.

摘要： Techniques for dynamically mapping assigned resources to physical resources are described herein. In one design, a resource assigned for communication may be mapped to a first physical resource based on a first mapping function and to a second physical resource based on a second mapping function. The assigned resource may be configurable for hopping or no hopping. The first mapping function may be a transparent function or may map consecutive input indices to non-consecutive output indices. The second mapping function may be equal to an output of the first mapping function plus an offset defined by a step size and a hop value. The hop value may be configurable for the assigned resource and may be conveyed in a resource assignment. The hop value may be set to a first value to indicate no hopping or to a second value to indicate hopping by the step size.

摘要： Disclosed are methods and apparatus for sampling rate conversion in a wireless transceiver. The methods and apparatus achieve agile setting of sampling rates or resampling by adaptively setting a sampling rate of a signal based on at least one performance requirement of the transceiver. In particular, the methods and apparatus perform sampling of an input signal at a first sampling rate to gain one or more input signal samples. The input signal samples are then filtered using parallel or polyphase filtering operating at a second sampling rate lower than the first sampling rate. The filtered samples are then interpolated at the second sampling rate to achieve resampling of the input signal. Polyphase filtering affords an effectively high input sampling rate for good spectrum image rejection, while allowing the second sampling rate to be effectively much lower than the first rate, thereby reducing the complexity of multiplier operations for interpolation.

摘要： Certain embodiments of the present disclosure provide techniques for approximate computation of l 2 norms as a part of the maximum likelihood (ML) detection: tri-maxmin, maxsum and sortsum algorithms. The proposed approximation schemes show better accuracy than conventional approximation schemes - the abssum and maxmin algorithms, while the computational complexity is very similar. The error rate performance of the ML detection that utilizes proposed norm-approximation techniques are very close to the reference ML detection with exact calculation of l 2 norms, while the computational complexity is significantly smaller.

摘要： A "post-squaring" detection algorithm, and related devices, that may reduce the complexity of maximum likelihood detection (MLD) schemes while preserving their performance is provided. Rather than search for optimum metrics (such as minimum distance metrics) based on squared norm values, a search may be based on un-squared norm metrics, and the squaring may be postponed, for example, until subsequent log-likelihood ratio (LLR) computation. For certain embodiments, approximations of un-squared norm values may significantly reduce computation complexity.
摘要翻译：提供了可以降低最大似然检测（MLD）方案的复杂性同时保持其性能的“后置”检测算法和相关设备。搜索可以基于平方范数，而不是基于平方范数搜索最佳度量（例如最小距离度量），并且可以延迟平方，例如直到后续的对数似然比（LLR）计算。对于某些实施例，非平方范数值的近似可以显着降低计算复杂度。
