    摘要: A method of wireless communication in a dual subscriber identification module (SIM) terminal includes transmitting a first synchronization message from a first module associated with a first SIM. The method also includes receiving a first acknowledgment (ACK) message on a fast physical access channel (FPACH) in response to the first synchronization message. The method further includes sharing timing information included in the first ACK between the first module and a second module.

    摘要: Equalization techniques are disclosed to reduce intersymbol interference of a received signal. Intersymbol interference is reduced by feedforward filtering and adjusting the input to the feedforward filter with feedback. This approach facilitates the removal of intersymbol interference from sparse signal portions before sparseness is undermined by other equalization procedures. Also, multiplication operations may be reduced and limited multiplier resources more effectively allocated by applying a threshold test to various multiplier coefficients associated with the equalization technique.

    摘要: Exemplary embodiments are directed to wireless power transfer. A transmitter generates an electromagnetic field at a resonant frequency with a transmit antenna to create a coupling-mode region within a near field of the transmit antenna. The transmitter defines a beginning of a recurring period by on-off keying the electromagnetic field during a synchronization portion of the recurring period. During a power transmission portion of the recurring period, the transmitter couples portions of the electromagnetic field to different receive antennas of various receiver devices within the coupling-mode region. The transmitter also determines a power allocation within the recurring period for the various receiver devices disposed within the coupling-mode region and adjusts a power level of the near field radiation responsive to power requirements received from the receiver devices.
