Abstract: A UWB impulse receiver including an RF stage followed by a baseband processing stage. The baseband processing stage includes a Rake filter including a plurality of time fingers, each finger including an integrator of the baseband signal during an acquisition window, a control module, and a detection module estimating the received symbols from the integration results. During a synchronization phase, the control module drives respective positions of the acquisition windows associated with the different fingers, to scan at a reception interval, the RF stage only operating, in a course of the synchronization phase, during the plurality of acquisition windows.

Abstract: Performing concurrent data communication and voice call monitoring using a single cellular radio. According to some embodiments, the UE may perform data communication, via the radio, using a first RAT, supported by a first SIM. The UE may also perform paging functions for a voice communication, via the radio, using a second RAT, supported by a second SIM. In some scenarios, the first and second RATs are the same. The data communication and the paging functions may be performed concurrently using shared physical layer resources. For example, the shared physical layer resources may comprise a shared software defined radio (SDR) configured to demodulate and/or decode signals of the data communication and the paging function. As another example, the shared physical layer resources may comprise a shared Rake receiver configured to demodulate signals of the data communication and the paging function.

Abstract: A multi-mode receiver includes a channel decomposition module (e.g., a Rake receiver) for separating a received signal into multipath components, an interference selector for selecting interfering paths and subchannels, a synthesizer for synthesizing interference signals from selected sub channel symbol estimates, and an interference canceller for cancelling selected interference in the received signal. At least one of the channel decomposition module, the synthesizer, and the interference canceller are configurable for processing multi-mode signals.
