  • Publication number: 20100229229
    Abstract: A system that allows indirect access of a network by TE, comprising TE device information; a personal network (PN) server; a master UE of a personal network; a TE of a personal network; and a UE B connected to a WAN which forwards data to and from TEs. Using the master UE the user sets configuration details which is the TE device information and stored at the PN Server. The TE device information contains data which is used to allow and control access of TE to the network, when the TE uses other UEs to access the network. When the TE tries to access the network through another UE B, the PN Server uses the TE device information to authenticate and control access of TE. UE B acts as a forwarding device in this sequence between TE and the PN server.

  • Publication number: 20100220770
    Abstract: A transmitter apparatus capable of reducing the distortions of vector modulated waves. This apparatus includes variable coefficient filters (110,112) in a stage preceding an amplitude signal voltage generating part (104) and also includes variable coefficient filters (111,113) in a stage preceding a phase modulated wave generating part (105). These variable coefficient filters (110-113) are used to perform a pulse shaping, thereby adjusting the delay between an amplitude component modulated signal (r(t)) and a phase component modulated signal (SC(t)) whereby a resolution, which is finer than the sampling period of a signal processing, can be used to adjust the delay time difference between the amplitude component modulated signal (r(t)) and the phase component modulated signal (SC(t)). As a result, the distortions of vector modulated waves (Srf(t)) can be reduced to a sufficiently small level.
