  • Patent number: 10277290
    Abstract: Non-linear or linear precoding is used to create separate areas of coherence to different users. Limited feedback techniques may also be employed to send channel state information (CSI) from the plurality of users to the MU-MAS. In some embodiments, a codebook is built based on basis functions that span the radiated field of a transmit array. Additionally, the precoding may be continuously updated to create non-interfering areas of coherence to the users as the wireless channel changes due to Doppler effect. Moreover, the size of the areas of coherence may be dynamically adjusted depending on the distribution of users.

  • Publication number: 20190083890
    Abstract: A system and method are described below for encoding interactive video used in video games streamed from a server to a client. For example, one embodiment of a computer-implemented method for performing video compression, and detecting a maximum data rate of a communication channel between a server and a client. The method includes transmitting a video stream comprising a series of compressed frames from the server to the client. The method includes detecting that the maximum data rate will be exceeded if a particular frame or frames of the sequence of frames are transmitted from the server to the client over the communication channel. The method includes reducing the frame rate of the video stream by adjusting compression of the video frames being sent from the server to the client to avoid exceeding the maximum data rate.

  • Publication number: 20190060747
    Abstract: Methods for hosting low-latency streaming interactive audio/video (A/V) include executing one or more video games or applications on a server communicatively coupled to a data network. Packet streams are received from a plurality of users and routed to the one or more video games. The packet streams include user control input that are used to compute A/V data in response. The A/V data are received from the video games or applications. Portions of the A/V data are compressed in parallel using processing units resulting in low-latency streaming compressed A/V data. The low-latency streaming compressed A/V data are routed to each of the users over a corresponding data network communication channel. The executing of video games, receiving of packet streams and A/V data, compressing portions of the A/V data and routing the compressed A/V data are performed with a latency such that at least one user has the perception that the controlled video game is responding instantly.

  • Patent number: 10200094
    Abstract: A system and method are described herein employing a plurality of distributed transmitting antennas to create locations in space with zero RF energy. In one embodiment, when M transmit antennas are employed, it is possible to create up to (M?1) points of zero RF energy in predefined locations. In one embodiment of the invention, the points of zero RF energy are wireless devices and the transmit antennas are aware of the channel state information (CSI) between the transmitters and the receivers. In one embodiment, the CSI is computed at the receivers and fed back to the transmitters. In another embodiment, the CSI is computed at the transmitter via training from the receivers, assuming channel reciprocity is exploited. The transmitters may utilize the CSI to determine the interfering signals to be simultaneously transmitted. In one embodiment, block diagonalization (BD) precoding is employed at the transmit antennas to generate points of zero RF energy.
