  • Publication number: 20210227546
    Abstract: The present disclosure relates to the field of communications technologies, and discloses a channel quality information determining method, an apparatus, and a system. The method may include: a terminal device obtains a configured TBS, and/or determines channel quality information of each of K segments of frequency domain resources based on the configured TBS and/or a time domain resource range. A frequency domain resource of the terminal device may be divided into N segments, where both N and K are integers greater than or equal to 1, and K is less than or equal to N. In some embodiments, the configured TBS may be fully considered when the channel quality information is determined, so that a network device properly may determine, based on the channel quality information, a frequency domain resource used to transmit a data packet.

  • Publication number: 20210019213
    Abstract: Systems and methods for AI assisted analysis of a user experience study are provided. A study objective (a goal of the study) and data relating to all possible navigation routes within a digital interface are received. Simulated clickstreams for navigating from any state of the digital interface to the study objective are generated. This simulated clickstream data is then used to train one or more machine learning models to determine a most efficient path to achieve the study objective from any state of the digital interface. Subsequently, study results from many different participants is received. Key events are then identified within the study results. Additionally, the likelihood of failure for each of the plurality of study results is predicted using the machine learning model, and information density of the plurality of study results is determined.

  • Publication number: 20200320558
    Abstract: Systems and methods for generating, administering and analyzing a click test study are provided. This includes uploading a static image and selecting portions of the static image as answers. The study author also generates a prompt for a participant, which is then presented, along with the static image. The participant then clicks with a cursor, or other selection mechanism, and the selection location(s) are recorded. Delay between the prompt display and the click is measuring in some embodiments. The recorded clicks are used to generate a heat map when aggregated with the results of other users. Likewise, the at least one click location may be compared to the selected portions to generate success metrics. In addition to the regular heat map, a high-contrast negative image heat map may likewise be generated.

  • Publication number: 20200311607
    Abstract: Systems and methods for improving an algorithm using physically or logically partitioned datasets, in compliance with use restrictions, is provided. The datasets belong to various customers in local data modules. A policy database is queried for use restrictions (contractual or legal) on the partitioned datasets. The datasets are then cataloged, and a set of functionalities are generated and then deployed. This deployment may include running the functionality on a central system on partitions of the datasets adhering to the restrictions, or packaging the functionality into discrete bins for each of the datasets, and delivering the bins to local computational devices at each local data module. The output of the functionalities are then aggregated, typically with a weighted function, and then used to train a unified algorithm.

  • Publication number: 20200210497
    Abstract: Advanced user experience study can be accomplished by enabling recording on a device such as a smart phone, providing a participant with one or more survey questions and a task. Typically, the participants are recorded and redirected to a starting URL. The recording can be terminated when the participant reaches a validation condition. Results, for example, videos, survey results, click flows, and heat maps may be filterable across any participant feature or any study validation criteria. Validation criteria includes time taken to complete a given action, ending up at a particular URL (or class of URLs), based upon question answers, or any combination thereof. These criteria can be classified as either a successful completion of the study, or a failed attempt. Additionally, the validation criteria can also include a decision by the participant to abandon the study.

  • Patent number: 8929495
    Abstract: A method for equalizing the received signal in communications based on filterbank multicarrier modulations and, more particularly, to such a method and system especially advantageous in situations where the channel frequency selectivity is exceptionally high. The method significantly improves the performance of traditional filterbank equalization algorithms based on finite impulse response filters at the output of the receive filterbank. Furthermore, the system consists of multiple parallel stages, the number of which can be tuned to achieve a good compromise between performance and computational complexity. Thanks to this modular structure, and to the fact that most of the architecture can be efficiently implemented using fast Fourier transforms, the system presents a very low computational complexity compared to more traditional equalizers for filterbank multicarrier modulations.

  • Patent number: 8290459
    Abstract: Method and device for detecting a target spectrum and its frequency location in a scenario contaminated with strong jammers on other interferers. The detection is based on the geodesic distance between the correlation matrix (RD) of the received signal and the correlation matrix (RT) of the target spectrum (TS) which is assumed known in shape and bandwidth. The detection happens when the threshold (Formula (I)) is overcome. The frequency location is based on the minimization of the mean square error between RD and RT.

  • Patent number: 7982670
    Abstract: The present invention relates to a method and a system for determining the direction of arrival of one or multiple radio or acoustic waves and, more particularly, to such a method and system especially advantageous in situations where the number of available observations is small and/or the available observations are received with low power. The method significantly improves the performance of traditional subspace signal processing algorithms in the low sample size regime. The algorithm is specifically designed to provide consistent estimates even when the observation dimension has the same order of magnitude as the number of observations. This guarantees a good behavior in finite sample size situations, where the number of sensors or antennae and the number of samples have the same order of magnitude or in scenarios where the received signal power is not sufficiently high to guarantee detection via conventional one-dimensional search methods.
