    摘要: When a speaker-independent voice-recognition (SIVR) system recognizes a spoken utterance that matches a phonetic representation of a speech element belonging to a predefined vocabulary, it may play a synthesized speech fragment as a means for the user to verify that the utterance was correctly recognized. When a speech element in the vocabulary has more than one possible pronunciation, the system may select the one most closely matching the user's utterance, and play a synthesized speech fragment corresponding to that particular representation.

    摘要: A method in a Multiple-Input Multiple-Output (MIMO) transmitter includes selecting a transmission mode from a group of modes including a spatial multiplexing mode and a transmit diversity mode. A rate matching parameter is set depending on at least the selected transmission mode. Data for transmission is formatted in one or more transport blocks, each transport block including multiple code blocks having respective lengths, in symbols, that are respective integer multiples of the rate matching parameter. The code blocks of a given transport block are mapped onto time-frequency resource elements in accordance with the selected transmission mode, such that each resource element contains data originating from only a respective one of the code blocks of the given transport block. The code blocks of the given transport block are transmitted over the time-frequency resource elements to a receiver.

    摘要: A method includes receiving a signal via multiple receive antennas. A noise covariance matrix, which indicates noise correlations between pairs of the receive antennas, is estimated. A stability criterion defined over the noise covariance matrix is evaluated, and the noise covariance matrix is modified when the stability criterion is violated. The received signal is processed using the modified noise covariance matrix.

    摘要: A user device on a wireless network includes a receiver, a noise detector and a noise determiner. The receiver receives downlink data communications from a base station that indicates an allocation of time/frequency resource blocks at least to user devices that are communicating with the base station. The noise detector measures noise in a time/frequency resource block, comprising plural time/frequency bins, that is not allocated to one of the user devices. The noise determiner determines a level of interfering noise based on noise in the resource block that is not allocated to one of the user devices.
