摘要:
The present invention provides systems and methods for parallel interference suppression. In one embodiment of the invention, a processing engine is used to substantially cancel a plurality of interfering signals within a received signal. The processing engine includes a plurality of matrix generators that are used to generate matrices, each matrix comprising elements of a unique interfering signal selected for cancellation. The processing engine also includes one or more processors that use the matrices to generate cancellation operators. A plurality of applicators applies the cancellation operators to parallel but not necessarily unique input signals to substantially cancel the interfering signals from the input signals. These input signals may include received signals, interference cancelled signals and/or PN codes.

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.

A receiver includes a first finger that receives a non-interference-cancelled signal and output first demodulated data, a first phase estimate, and a first PN code. The receiver also includes a second finger that selectively receives the non-interference-cancelled signal and a first interference-cancelled signal generated from the non-interference-cancelled signal based on the first phase estimate and the first PN code. The second finger also outputs second demodulated data.

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.

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.
