  • Patent number: 10257013
    Abstract: A method of modulating and demodulating superposed signals for MUST scheme is proposed. A transmitter takes bit sequences intended for multiple receivers under MUST scheme to go through a “bit sequence to constellation points” mapper before entering the modulators to satisfy the Gray coding rule and to achieve high demodulation performance for the receivers. In a first method, each bit sequence is assigned for each constellation point on the constellation map to satisfy one or more conditions under different power split factors. In a second method, the constellation map is divided into sub-regions according to the clustering of the constellation points for bit sequence assignment. A near-UE may use an ML receiver for demodulation and decoding the superposed signal. A far-UE may use an ML receiver or an MMSE receiver for demodulation and decoding the superposed signal.

  • Patent number: 10063341
    Abstract: Methods and apparatus for transmitting Ethernet data along an Ethernet link with a BASE-T transceiver are disclosed. One exemplary BASE-T Ethernet transceiver includes an Ethernet data framing module having an input interface to receive Ethernet block data bits at a first data rate. Logic associates the Ethernet block data bits with an auxiliary bit and a number of zero bits. An error encoder is coupled to the logic to encode all of the data bits, auxiliary bit and zero bits into an error encoded transport frame having plural error check bits. A symbol mapper receives the error encoded transport frame and transforms the error encoded transport frame into multiple symbols. A transmitter coupled to the symbol mapper transmits the multiple symbols over an Ethernet link at one of a selection of symbol rates. The data rate of data transmitted over the Ethernet link is based on the number of zero bits.

  • Patent number: 9998995
    Abstract: A method for reducing self-interference in a wireless network, such as a Link 16 network, while maintaining simultaneous multiple access takes advantage of the physical proximity of nodes in a localized subnetwork, such as a fighter-to-fighter subnetwork in a flight wing, by actively reducing the transmit powers used for subnet messages between the nodes. Calibration messages such as Precise Participant Location and Identification (PPLI) messages are exchanged between all of the nodes of the localized subnetwork, from which each node determines the identities, transmit powers, noise levels, and SNRs of all of the other nodes. The node then determines a link margin for other nodes, and sets its transmit power to a “safe” level for the subnetwork according to the lowest link margin.
