    摘要: The invention proposes a smart card which comprises a digital signal processing receiver that can automatically identify the type of a smart card reader based on the error vector magnitude of signals received from the reader. The digital signal processing receiver is able to reconfigure itself at runtime in order to optimally minimize its power consumption in dependence on the type of reader it is communicating with. Furthermore, the invention proposes a new preamble structure that comprises a basic part and an optional additional part.

    摘要: A base station includes a millimeter wave communication unit coupled to an impulse radio ultra-wideband (IR-UWB) communication unit. The millimeter wave communication unit is capable of being wirelessly coupled to user-equipment using a millimeter wave communication link. Based on a determination as to whether the user-equipment is configured for IR-UWB ranging and localization, an IR-UWB communication link is established between the base station and user-equipment for IR-UWB ranging and localization. When the IR-UWB communication link is established for IR-UWB ranging and localization, the ranging and localization associated with the millimeter wave communication unit is disabled and the millimeter wave communication link is used for data communication maximizing throughput by utilizing localization and ranging information provided by the IR-UWB communication link.

    摘要: Embodiments of a method for processing a baseband signal in a Direct Current (DC)-suppressed system, a system for processing a baseband signal in a DC-suppressed system, and a smart card are described. In one embodiment, a method for processing a baseband signal in a DC-suppressed system involves processing the baseband signal in the analog domain with a first high pass filter (HPF), converting the processed baseband signal to a digital signal, and processing the digital signal in the digital domain with a second HPF to provide a discrete-time differentiation of the baseband signal. Other embodiments are also described.
