  • Patent number: 11329733
    Abstract: A system and method are configured to check the health of a TETRA-based communication system without interrupting or degrading the operation of the TETRA base station. The health is checked by at least measuring an uplink RSSI of the TETRA base station and determining a transmitted power level and a location of a transmitter. The measured RSSI is used to determine a strongest RSSI and to obtain the transmitted power level and location of a transmitter corresponding to the strongest RSSI.

  • Patent number: 11258641
    Abstract: Optimized continuous time linear equalization (CTLE) circuit parameters for a received signal are found using an iterative search process. The received signal is repeatedly sampled by an analog-to-digital converter (ADC). Certain samples containing interference that cannot be cancelled by a CTLE in the sampled series are filtered out (discarded). The remaining samples are used to generate, over a selected evaluation window, a histogram of the sampled values. This histogram is used to calculate a figure of merit for the current CTLE parameter settings. The figures of merit for various CTLE parameter settings are compared to find the set of CTLE parameter settings that optimize the figure of merit and by extension, optimize the CTLE circuitry's performance at equalizing the received signal.

  • Patent number: 11108474
    Abstract: Systems and methods for testing a wireless device having a beamforming circuit are disclosed herein. An exemplary system includes a shielded test enclosure, a wireless channel emulator, and a test instrument. The shielded test enclosure provides a cable-free connection between the wireless device and the wireless channel emulator, thereby allowing for testing of various types of wireless devices, particularly those that do not have radio-frequency (RF) connectors. The shielded test enclosure is smaller in size and less-expensive than traditional multi-probe anechoic chambers. In one example application, the shielded test enclosure is used to house a multiple-input multiple-output (MIMO) antenna array of a wireless device and a probe antenna array. The probe antenna array is coupled to the wireless channel emulator and used to receive signals from MIMO antenna arrays of various sizes thereby eliminating the need to uniquely tailor the probe antenna array to any specific MIMO antenna array.

  • Patent number: 11070794
    Abstract: In a video quality assessment method, an assessment model is first generated based on a subjective assessment result of a user on each sample in a sample set and based on a parameter set (a parameter type in the parameter set may include at least one of a packet loss rate, a delay, and a jitter) of each sample. Therefore, when video quality is being assessed, a parameter set of a to-be-assessed video is obtained first, where the parameter set of the to-be-assessed video has a same parameter type as the parameter set of each sample that is used to generate the assessment model; and then video quality of the to-be-assessed video is assessed based on the assessment model and the parameter set of the to-be-assessed video, to obtain an assessment result.

  • Patent number: 10978130
    Abstract: Methods, systems, and devices for temperature-based access timing for a memory device are described. In some memory devices, accessing memory cells may be associated with different operations that are variously dependent on a temperature of the memory device. For example, some operations associated with accessing a memory cell may have a longer duration and others a shorter duration depending on the temperature of the memory device. In accordance with examples as disclosed herein, a memory device may be configured for performing some portions of an access operation according to a duration that is proportional to a temperature of the memory device, and performing other portions of the access operation according to a duration that is inversely proportional to a temperature of the memory device.

  • Patent number: 10917203
    Abstract: Embodiments use Bayesian techniques to efficiently estimate the bit error rates (BERs) of cables in a computer network at a customizable level of confidence. Specifically, a plurality of probability records are maintained for a given cable in a computer system, where each probability record is associated with a hypothetical BER for the cable, and reflects a probability that the cable has the associated hypothetical BER. At configurable time intervals, the probability records are updated using statistics gathered from a switch port connected to the cable. In order to estimate the BER of the cable at a given confidence level, embodiments determine which probability record is associated with a probability mass that indicates the confidence level. The estimate for the cable BER is the hypothetical BER that is associated with the indicated probability mass. Embodiments store the estimate in memory and utilize the estimate to aid in maintaining the computer system.

  • Patent number: 10904050
    Abstract: Systems and methods for classifying a modulation scheme of a wireless signal are described. In some embodiments, a system receives a wireless signal modulated based on a modulation scheme having a constant modulus. The system can generate a resampled signal from the wireless signal based on features extracted from the wireless signal and perform blind equalization on the resampled signal based on a constant modulus criterion to generate an equalized signal. Then, the system can cause a modulation classifier to classify the received wireless signal to a modulation scheme from a plurality of predetermined modulation schemes based on the equalized signal. By preconditioning the wireless signal to reduce feature variability imparted by a propagation channel onto the wireless signal, the system can increase the classification accuracy of the modulation classifier.
