Frame structures, transmitters, and receivers utilizing dual subcarriers for signal adjustment
Examples of wireless OFDM communication systems are described herein which replace pilot subcarriers having known modulation with lower dual subcarriers. At the transmitter, for each resource block, the bits that modulate a few payload subcarriers are selected and then encoded with a short dual code thereby forming dual systematic bits and dual check bits. Such selected payload subcarriers are designated as upper dual subcarriers and the dual check bits modulate the lower dual subcarriers, At the receiver, for each resource block, the dual subcarriers are phase adjusted, demodulated, decoded using the short dual code, and re-modulated thereby forming the original dual subcarrier modulation without phase noise nor channel impairments. The re-modulated dual subcarriers are compared against the received dual subcarriers for channel estimation or carrier phase-locked-loop purposes. For example, prior-art OFDM systems with 4 pilots per resource block could be replaced with 8 dual subcarriers for a rate 1/2 short dual code. An increase in the number of subcarriers used for channel estimation or carrier phase-locked-loop tracking has less error in the channel estimate or phase estimate. Lower error permits lower payload BER, lower transmit power, or wider PLL bandwidth to track higher Doppler frequency shifts. |

Facilitating fast channel state information computation for 5G wireless communication systems
Fast calculation of channel state information using demodulation reference signals (DM-RS) is provided herein. Channel state information is traditionally calculated based on the channel state reference signals (CS-RS). Demodulation reference signals, which are used for channel estimation for a data channel, are transmitted at different times than CS-RS however, and so some portions of the channel state information including layer indicator (LI) and channel quality indicator (CQI) can be calculated based on the demodulation reference signals, allowing a network to adapt more quickly to changing channel conditions, without having to transmit a CS-RS. Generally, precoding matrix indicator and rank indicator, which cannot be determined based on the DM-RS, don't change as often and are more stable over time, thus do not need to be calculated as frequently as the LI and CQI. |

An electrokinetically pumped sheath flow nanospray interface for capillary electrophoresis coupled to negative mode electrospray mass spectrometer is described.

Low latency nearby group translation
Local wireless networking is used to establish a multi-language translation group between users that speak more than two different languages such that when one user speaks into his or her computing device, that user's computing device may perform automated speech recognition, and in some instances, translation to a different language, to generate non-audio data for communication to the computing devices of other users in the group. The other users' computing devices then generate spoken audio outputs suitable for their respective users using the received non-audio data. The generation of the spoken audio outputs on the other users' computing devices may also include performing a translation, thereby enabling each user to receive spoken audio output in their desired language in response to speech input from another user, and irrespective of the original language of the speech input. |

Voice-based operations
Described embodiments provide systems and methods for capture and translation of voice commands into user interface commands and gestures. A transducer of a device, such as a microphone, may receive an audible or spoken command from a user and may translate the input audio into text via a speech-to-text engine, either as part of the operating system of the device or via a separate agent (which may be executed by the device or a remote server). The text may be interpreted via a natural language parser (either on the device or the remote server) to identify a command, such as scrolling, panning, zooming, or other such gestures. A context may be retrieved, such as coordinates of a cursor or other interface element within a hosted application or SaaS application, and the command may be applied based on the coordinates of the cursor. |

Dynamic contact ingestion
Techniques for dynamic contact ingestion are described. A system may interpret a voice command received from a first device based on contact data or other information associated with a second device connected to the first device. For example, when a data connection is made between the first device and the second device, the first device may receive the contact data and send the contact data to a remote system. The remote system may temporarily associate the contact data with the first device, enabling the remote system to interpret a voice command received from the first device using the contact data. The remote system may use the contact data to perform disambiguation, enabling the remote system to initiate outbound calls, announce inbound calls, and/or the like. When the second device is disconnected from the first device, the remote system may remove the association between the contact data and the first device. |
