    Abstract: A system for selecting a communication mode for a transmitting node to communicate with a receiving node in a mesh network is provided. For example, a transmitting node can gather mode selection data that describe communication conditions of the transmitting node and the receiving node. Based on the mode selection data, the transmitting node can determine a first white list of modes that can be used by the transmitting node to successfully transmit data packets to the receiving node. The transmitting node also determines a second white list of modes that can be used by the receiving node to send acknowledgment packets successfully to the transmitting node. The transmitting node further identifies overlapped modes between the first and second white lists of modes. The transmitting node can then select one of the overlapped modes for transmitting data packets to the receiving node.

  • Patent number: 10972215
    Abstract: A communication system in which probabilistic signal shaping and FEC coding are jointly applied in a manner that enables the use of substantially any constellation template, e.g., a template in which the constellation symbols include a constellation symbol of zero amplitude and/or are arranged in an asymmetric manner. In an example embodiment, the transmitter's electronic encoder can be configured to apply two different respective shaping codes to the information bits and to the corresponding parity bits. The resulting shaped streams can then be appropriately multiplexed and transmitted over the optical communication channel to realize a significant shaping gain. Advantageously, the constellation template(s), two distribution matchers, and FEC code can be flexibly selected and/or adapted to achieve nearly optimal system operation under substantially arbitrary (e.g., arbitrarily bad) channel conditions.

  • Patent number: 10959114
    Abstract: Fiber, cable, and wireless data channels are typically impaired by reflectors and other imperfections, producing a channel state with echoes and frequency shifts in data waveforms. Here, methods of using OTFS pilot symbol waveform bursts to automatically produce a detailed 2D model of the channel state are presented. This 2D channel state can then be used to, optimize data transmission. For wireless data channels, an even more detailed 2D model of channel state can be produced by using polarization and multiple antennas in the process. Once 2D channel states are known, the system turns imperfect data channels from a liability to an advantage by using channel imperfections to boost data transmission rates. The methods can be used to improve legacy data transmission modes in multiple types of media, and are particularly useful for producing new types of robust and high capacity wireless communications using non-legacy OTFS data transmission methods.

  • Patent number: 10728786
    Abstract: A method and poll control entity (300) for controlling a polling procedure in a radio communication where a data transmitting node (302) transmits data (3:1) to a data receiving node (304) and sends polls to the data receiving node according to a default polling frequency. The polls require the data receiving node to send feedback (3:2) to the data transmitting node indicating whether said data has been received and decoded by the data receiving node or not. The poll control entity detects (3:3a-c) a trigger of the radio communication indicating a deviation of a feedback time which is a time period between a time of sending the poll and a time of receiving the feedback from an expected feedback time range. The poll control entity then adjusts (3:4) the polling frequency based on the detected trigger such that the deviation of the feedback time is reduced, and enforces (3:5) the adjusted polling frequency at the data transmitting node.
