摘要： The present invention is a high efficiency permanent magnet machine capable of maintaining high power density. The machine is operable over a wide range of power output. The improved efficiency is due in part to copper wires with a current density lower than traditional designs and larger permanent magnets coupled with a large air gap. In a certain embodiment, wide stator teeth are used to provide additional improved efficiency through significantly reducing magnetic saturation resulting in lower current. The machine also has a much smaller torque angle than that in traditional design at rated load and thus has a higher overload handling capability and improved efficiency. In addition, when the machine is used as a motor, an adaptive phase lag compensation scheme helps the sensorless field oriented control (FOC) scheme to perform more accurately.

摘要： A method, transmitter node, and receiver node for communicating a transport block of information bits from the transmitter node to the receiver node are provided. The transmitter node encodes the information bits and divides the coded bits into antenna selection bits and modulation bits. The antenna selection bits are used to select a transmit antenna from a plurality of transmit antennas. The modulation bits are used by a modulator to select modulation symbols for transmission utilizing the selected antenna. The receiver node receives the radio signal with a front-end receiver and computes a plurality of combined signals, each corresponding to one hypothesized transmit antenna at the transmitter node. The receiver forwards the plurality of combined signals to a soft value computer, which computes soft values for the antenna selection and modulation bits. The soft values are combined and decoded to produce decision bits for recovering the transport block.

摘要： A method in a terminal for providing an ACK/NAK message to a base station is provided. The terminal counts the number of assigned downlink subframes detected from the base station resulting in k. The terminal then establishes whether each of a number of transport blocks comprised in the counted k downlink subframes is correctly received or not. In the case when each one of the transport blocks, comprised in the k downlink subframes is estimated as correctly received the terminal provides to the base station an encoded ACK message for the k subframes, which comprises k, the number of subframes.
