  • Patent number: 11296808
    Abstract: An interference canceller comprises a composite interference vector (CIV) generator configured to produce a CIV by combining soft and/or hard estimates of interference, an interference-cancelling operator configured for generating a soft projection operator, and a soft-projection canceller configured for performing a soft projection of the received baseband signal to output an interference-cancelled signal. Weights used in the soft-projection operator are selected to maximize a post-processing SINR.

  • Patent number: 10153805
    Abstract: 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.

  • Patent number: 9735816
    Abstract: Interference is cancelled from a baseband signal by synthesizing interference from estimated symbols in interfering subchannels. The estimated symbols are hard-coded, soft weighted, or zeroed, depending on the value of an estimated pre-processed signal-to-interference-and-noise ratio (SINR) in each subchannel in order to maximize a postprocessed SINR. The estimated pre-processed SINR is obtained from averages of estimated symbol energies and estimated noise variances, or from related statistical procedures.

  • Patent number: 9323296
    Abstract: A system, a method and an apparatus are described. The apparatus includes a modem that responds to a thermal mitigation request by invoking different levels of thermal mitigation for different concurrently active connections. In some instances, the modem may invoke thermal mitigation with respect to a first active connection and refrain from invoking thermal mitigation with respect to a second active connection maintained by the modem. The apparatus determines the first and second active connections based on subscriptions corresponding to subscriber identification modules, an identification of a power amplifier or group of power amplifiers responsible for a thermal issue in the modem. The selection of mitigation levels for each active connection and decisions to invoke mitigation on one connection while refraining from invoking mitigation on another connection may be based on priorities of the active connections, including quality of service related priorities.

  • Patent number: 9270325
    Abstract: A receiver is configured for canceling intra-cell and inter-cell interference in coded, multiple-access, spread-spectrum transmissions that propagate through frequency-selective communication channels. The receiver employs iterative symbol-estimate weighting, subtractive cancellation with a stabilizing step-size, and mixed-decision symbol estimate. Receiver embodiments may be implemented explicitly in software of 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 of subchannel symbol level).

  • Patent number: 9237535
    Abstract: Aspects of the present disclosure generally relate to wireless communications and, more particularly, to performing channel estimation with modifications for improved system performance. Aspects generally include receiving, at a user equipment (UE), reference signals from a base station in a current subframe, and performing channel estimation, wherein the channel estimation is based at least in part on the reference signals received in the current subframe, a mobility characteristic of the UE, and a configuration of subframes prior to the current subframe.

  • Patent number: 9172414
    Abstract: The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing robust receive (Rx) processing to resolve radio frequency coexistence interference between two subscriptions operating on the DSDA device. The DSDA device may detect when a subscription (the “aggressor”) de-senses the other subscription (the “victim”) as a result of the aggressor's transmissions, and in response, implement robust Rx processing to mitigate the effects of de-sense on the victim while causing minimal impact to the aggressor.

  • Patent number: 9154963
    Abstract: A method and apparatus of wireless communication are configured to capture, at a user equipment, one or more adjacent Universal Mobile Telecommunication System Terrestrial Radio Access Absolute Radio Frequency Channel Numbers (UARFCNs), extract a useful wide band signal from the one or more adjacent UARFCNs, perform a PSCH search on the useful wide band signal to obtain a composite PSCH signal, and reject the one or more UARFCNs where no peaks greater than a noise threshold are detected in the composite PSCH signal.
