Abstract: Techniques described herein are directed to the enhancement of spectral features of an audio signal via adaptive modulation filtering. The adaptive modulation filtering process is based on observed modulation envelope autocorrelation coefficients obtained from the audio signal. The modulation envelope autocorrelation coefficients are used to determine parameters of an adaptive filter configured to filter the spectral features of the audio signal to provide filtered spectral features. The parameters are updated based on the observed modulation envelope autocorrelation coefficients to adapt to changing acoustic conditions, such as signal-to-noise ratio (SNR) or reverberation time. Accordingly, such acoustic conditions are not required to be estimated explicitly. Techniques described herein also allow for the estimation of useful side information, e.g.

Abstract: A wireless communication device (alternatively, device, WDEV, etc.) includes a processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. A WDEV selects a resource unit (RU) from an orthogonal frequency division multiple access (OFDMA) sub-carrier plan for use in supporting communications with another WDEV. The WDEV transmits a signal to the other WDEV that includes information that specifies the RU that is selected from the OFDMA sub-carrier plan and then supports communications with the other WDEV using the RU that is selected from the OFDMA sub-carrier plan. The OFDMA sub-carrier plan includes multiple OFDMA sub-carrier sub-plans of different sized RUs and null sub-carriers.

Abstract: A method for wireless communication between stations of differing protocols begins by determining whether protocols of target stations of a wireless communication are different than a protocol of a source station. The method continues by, when at least one of the target stations has a different protocol than the protocol of the source station, determining whether the wireless communication is a direct wireless communication or an indirect wireless communication. The method continues with the source station transmitting a frame to an access point, wherein the frame is formatted in accordance with the protocol of the source station, when the wireless communication is the indirect wireless communication. The method continues with the access point converting the frame into at least one alternate frame based on the protocol of the at least one of the target stations having the different protocol.

Abstract: Aspects of virtual field buffer based decoding are described. In one embodiment, a current picture field is read from a coded picture buffer comprising coded pictures of video, for example. The current picture may be associated with a top or bottom field polarity. According to decoding and picture output orders, the current picture field is assigned to an available field entry of a virtual field buffer, and an available frame index of a virtual frame map is assigned to the current picture field. The assignment of the available frame index to the current picture field is indicated to a decoder that decodes the current picture field with reference to the assigned frame index. According to aspects of the embodiments described herein, rather than determining complimentary picture fields after decoding, the assignment of complimentary picture fields to virtual frame indexes before decoding provides certain efficiencies.

Abstract: Systems and techniques for managing channel reservation in a full-duplex wireless network. A transmitting node sends a media access control frame to a receiving node, including an integrity check field in a header of the frame. Upon performing an integrity check and determining that the media access control frame is addressed to itself, the receiving node sends a transmission so as to reserve the channel. If the receiving node has no data to send, the transmission may be an acknowledgement field, and if the receiving node has data to send, the transmission may be a media access control frame including an integrity check field in a header of the frame.
