    Abstract: A system and a method are disclosed for noise power estimation in wireless communications. In some embodiments, the method includes: receiving a reference signal; generating a first channel estimate, based on the reference signal; calculating a first noise power estimate; calculating a corrected noise power estimate by applying a multiplicative correction based on a linear minimum mean square error filter weight to the first noise power estimate; receiving a transmission; and decoding the transmission, based on the corrected noise power estimate.

    Abstract: A system and method for storing a power delay profile in compressed form. In some embodiments, the method includes: identifying, in a power delay profile including a first group of taps, a first arrival tap corresponding to a first arrival path; identifying a first subset of taps, the first subset being a subset of the first group and including the first arrival tap; identifying a second subset of taps, the second subset being a subset of the first group and being disjoint from the first subset; and storing, in a memory, the union of the first subset and a proper subset of the second subset.

    Abstract: A system and method for configuring an RF network based on machine learning. In some embodiments, the method includes: receiving, by a first neural network, a first state and a first state transition, the first state including: one or more identifiers for available active ports, and a set of available connections between two or more circuit elements, each of the circuit elements being one of: (1) a first circuit type, (2) a second circuit type that operatively connects a circuit element of the first circuit type to one of the available active ports, and (3) the available active ports; and generating, by the first neural network, a first estimated quality value, for the first state transition.

    Abstract: A method may include generating an estimated time offset based on a reference signal in a communication system, and adjusting a transform window in the communication system based on the estimated time offset, wherein the estimated time offset is generated based on machine learning. Generating the estimated time offset may include applying the machine learning to one or more channel estimates. Generating the estimated time offset may include extracting one or more features from one or more channel estimates, and generating the estimated time offset based on the one or more features. Extracting the one or more features may include determining a correlation between a first channel and a second channel. The correlation may include a frequency domain correlation between the first channel and the second channel. Extracting the one or more features may include extracting a subset of a set of features of the one or more channel estimates.

    Abstract: Apparatuses and methods of manufacturing same, systems, and methods for blind detection of a numerology of a received signal are described. In one aspect, a method is provided for a user equipment (UE) to blindly detect the numerology of a received signal. The method includes correlating cyclic prefix (CP) signals in the received signal in the time domain based on a plurality of hypotheses of subcarrier spacing (SCS); measuring power variation of the received signal in the frequency domain based on the plurality of hypotheses of SCS; and combining weighted results of a correlation of the CP signals in the time domain and the measured power variation in the frequency domain to determine a numerology of the received signal for a corresponding hypothesis of SCS of the plurality of hypotheses.
