  • Methods and systems for beam steering crest factor reduction (CFR) clip noise
    Patent number: 8995570
    Abstract: Signal-to-noise ratios (SNRs) and/or amplifier performance can be improved in crest factor reduction (CFR) applications by steering clipping noise in a different direction than the data signal achieving upon reception. Indeed, using clipping noise signals that have a different amplitude-phase relationship than the input/baseline signal causes the clipping noise signal and data signal to exhibit different antenna patterns, effectively steering the clipping noise in a different direction than the data signal. For instance, clipping noise can be steered away from potential receivers to improve received signal quality. In addition, higher magnitude clipping noise can be used to achieve improved power amplifier performance without increasing received SNR.

  • Multiple switch power stage control tracking PCM signal input
    Patent number: 8988049
    Abstract: A DC power stage provides a power output that tracks a PCM signal input. A mapping unit generates an integer number of N digital PWM signals each switched at a same switching frequency by switching states of the PWM signals one at a time based on a level of the PCM signal input. An imbalance correction unit adjusts a duty ratio of the PWM signals relative to one another based on differentially accumulating errors among the PWM signals to prevent divergence of PWM signals. N corresponding switches therefrom switch power from a DC power source. N inductances in parallel produce a combined signal that is low pass filtered to provide the power output. Switching is between only those state combinations where the switching frequency is cancelled in the combined signal. The switching frequency is a sampling frequency of the PCM signal input divided by a product of 2 times N.

  • System and Method for User Equipment Cooperation
    Publication number: 20150082133
    Abstract: User equipment (UE) cooperation can be improved by relaying partial soft information to target UEs. More specifically, a cooperating UE may relay a subset of log-likelihood ratios (LLRs) to the target UE. The subset of LLRs may correspond to fewer than all resource blocks of the original transmission. This may allow UE cooperation to be effective when the cooperating UE was only able to decode a portion of the original transmission. This may also allow fewer network resources (e.g., bandwidth, etc.) to be used when the target UE does not need all of the soft information to decode the original transmission. Multiple cooperating UEs can provide different subsets of LLRs, and the subsets may or may not overlap with one another.
