Abstract: A method for controlling a first node transmitting a transmission message to a plurality of second nodes may be provided. The method includes dividing the transmission message into at least one sub-message, encoding the at least one sub-message to a data stream, determining a first transmission direction of the data stream toward at least one of the plurality of second nodes, based on a polynomial of a channel gain between the first node and the at least one of the plurality of second nodes, and transmitting the data stream to the at least one of the plurality of second nodes, based on the determined first transmission direction.

Abstract: Each of a first transmitter and a second transmitter uses a rate split scheme. Each of the first transmitter and the second transmitter may transmit at least four sub-messages, and different transmission powers may be allocated to the at least four sub-messages. Also, each of receivers may cooperate with each other, may share sub-messages that act as interferences, and may extract desired messages using the shared sub-messages.

Abstract: A method and apparatus to control interference in a relay node are provided and include simultaneously receiving a symbol from source nodes, adjusting channel coefficients; and relaying the symbol to destination nodes with adjusted channel coefficients. The simultaneously receiving and the relaying are performed during a symbol transmission process between the source and destination nodes.

Abstract: A method of controlling interference of relay nodes and node pairs in a multi-hop network, includes relaying signals received from source nodes among the node pairs to destination nodes pairing with the source nodes, and cancelling a part of interference signals between the node pairs by controlling channel coefficients of the relay nodes. The destination nodes are configured to cancel residual interference signals among the interference signals, using the signals received by the destination nodes.

Abstract: A memory device may include a power-up control circuit and a first set of boost voltage generators. The power-up control circuit may be configured to consecutively activate a first set of power-up signals with a first delay time between each power-up signal of the first set of power-up signals in response to a rise of a power supply voltage and a reset signal having a first logic level at an initial stage of power-up. The first set of boost voltage generators may be configured to generate an internal boost voltage based on an external boost voltage and the first set of power-up signals. The first set of boost voltage generators may be configured to activate before the reset signal transitions from the first logic level to a second logic level opposite to the first logic level.
