  • Publication number: 20080089403
    Abstract: Disclosed is a chip-level or a symbol-level equalizer structure for a multiple transmit and receiver antenna architecture system that is suitable for use on the WCDMA downlink. The equalizer structure takes into account the difference in the natures of inter-antenna interference and multiple access interference and suppresses both inter-antenna interference and multiple access interference (MAI). Enhanced receiver performance is achieved with a reasonable implementation complexity. The use of the CDMA receiver architecture, in accordance with this invention, enables the realization of increased data rates for the end user. The CDMA receiver architecture can also be applied in conjunction with space-time transmit diversity (STTD) system architectures.

  • Publication number: 20020030958
    Abstract: This invention relates to the protection against over-voltage situations in a telecommunications network. Especially, the invention relates to fault situations that are generated by a power distribution network. The idea of the invention is to protect the telecommunication equipment against any overvoltage caused by an external source. The invention uses a detector core around cables through which a common mode fault current goes. The subscriber line cables or the power & ground cables form a primary coil in a transformer. The transformer's secondary coil forms an output current, preferably for converting equipment that converts the fault current information into a suitable form for operational devices that perform a desired protection action.
