    摘要： A communication device and method include a reconfigurable receiver that is reconfigurable between communication, ranging and radar modes. The reconfigurable receiver includes a mixer configured to mix digital samples with a carrier phase estimate signal and configured to generate in-phase digital samples based on the carrier phase estimate. The reconfigurable receiver further includes a symbol correlator configured to correlate against the in-phase digital samples and generate correlated data, and a symbol binning unit configured to bin the correlated data and generate a first order channel impulse response estimate. The reconfigurable receiver yet further includes a multiplexer configured to switch the digital samples to the symbol binning unit when the reconfigurable receiver is configured in radar mode and to switch the correlated data to the symbol binning unit when the reconfigurable receiver is configured in a ranging mode.

    摘要： A multi-operator radio node for a communications system that supports sharing a common antenna array while supporting individual spectrum of multiple service providers. The multi-operator radio node includes signal processing circuits for each supported service provider. Each signal processing circuit is configured to receive communications signals for a supported service provider to be distributed through a common antenna array to wireless client devices. Each signal processing circuit includes a modem that processes the received communications signals for spectrum of its service provider to provide signal streams to be distributed to co-located antenna elements in the antenna array. Summation circuits are provided at the front end of each RF chain circuit to combine signal streams of the spectrum of the service providers directed to the same antenna element in the antenna array to form signal beams in individual spectrum layers of the service providers.

    摘要： This invention teaches to the details of an interference suppressing receiver for suppressing intra-cell and inter-cell interference in coded, multiple-access, spread spectrum transmissions that propagate through frequency selective communication channels to a multiplicity of receive antennas. The receiver is designed or adapted through the repeated use of symbol-estimate weighting, subtractive suppression with a stabilizing step-size, and mixed-decision symbol estimates. Receiver embodiments may be designed, adapted, and implemented explicitly in software or programmed hardware, or implicitly in standard RAKE-based hardware either within the RAKE (i.e., at the finger level) or outside the RAKE (i.e., at the user or subchannel symbol level). Embodiments may be employed in user equipment on the forward link or in a base station on the reverse link. It may be adapted to general signal processing applications where a signal is to be extracted from interference.

    摘要： 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.

    摘要： Certain aspects of a method and system for achieving space and time diversity gain are disclosed. Aspects of one method may include modifying a generalization code of at least one pilot channel, to measure signal strengths for each of a plurality of received multipath signals. A portion of the plurality of received multipath signals may be combined based on the measured signal strengths. The signal strengths of the plurality of received multipath signals may be measured on a primary pilot channel by assigning its generalization code to zero. The signal strengths of the plurality of received multipath signals on a secondary pilot channel may measured by assigning its generalization code to a non-zero value.
