  • Patent number: 11888670
    Abstract: Methods, systems, and devices for wireless communications are described. Techniques provide for reliable signal processing and amplification of downlink signals. A network entity may apply a digital pre-distortion (DPD) process to a signal for transmission to a user equipment (UE) and may apply a crest factor reduction (CFR) process to the output of the DPD process. The output of the CFR process may be amplified by a power amplifier and transmitted via a downlink transmission to the UE. The CFR process limits the peak power of the signal provided to the power amplifier (e.g., to a configured level), thereby reducing the peak to average power ratio (PAPR) of the signal provided to the power amplifier. The DPD process may compensate for non-linearities of the power amplifier. A training procedure for the DPD process may account for the CFR process applied after the DPD process.

  • Patent number: 11855669
    Abstract: A method for cancelling radio frequency interference (RFI) and a communication system thereof are provided. In the communication system, digital signals of a frequency domain are converted from analog signals and received by the communication system generally carry RFI, and the signals are processed by an equalizer and a far-end crosstalk canceller. Then, for preventing erroneous signals from forming due to an occurrence of a notch, masking parameters applied to the equalizer and the far-end crosstalk canceller are modified for not processing frequency bands that are RFI-affected. The frequency bands can be ignored by masking corresponding bins in the frequency domain after a fast Fourier transformation. The signals processed by the equalizer and the far-end crosstalk canceller are then outputted to an RFI canceller, and the signals with RFI cancellation can be obtained.

  • Patent number: 11842262
    Abstract: A design application is configured to generate a latent space representation of a fleet of pre-existing vehicles. The design application encodes vehicle designs associated with the fleet of pre-existing vehicles into the latent space representation to generate a first latent space location. The first latent space location represents the characteristic style associated with the fleet of pre-existing vehicles. The design application encodes a sample design provided by a user into the latent space representation to produce a second latent space location. The design application then determines a distance between the first latent space location and the second latent space location. Based on the distance, the design application generates a style metric that indicates the aesthetic similarity between the sample design and the vehicle designs associated with the fleet of pre-existing vehicles. The design application can also generate new vehicle designs based on the latent space representation and the sample design.
