    Abstract: A communication device includes an antenna array, and a beamforming controller configured to determine a set of beamforming weights for the antenna array based on a target radiation pattern having a plurality of main fingers, wherein the beamforming controller is configured to, in each of a plurality of iterations identify a search space of beamforming weights for a plurality of elements of the antenna array, and determine, based on contribution of one or more of the plurality of elements of to multiple of the plurality of main fingers, an updated set of beamforming weights in the search space to reduce a difference between an actual radiation pattern and the target radiation pattern, the antenna array configured to transmit or receive radio signals based on the updated set of beamforming weights.

    Abstract: The present disclosure includes systems and methods for supporting polar codewords with variable polar codeword lengths. Variable codeword length codewords are communicated using an n-bit encoder/n-bit decoder having n inputs and n corresponding outputs. Each input and each corresponding output is associated with a bit index. A set of bit indices to be shortened are selected. The encoder encodes n input bits to obtain n output bits. Each output bit that is associated with a bit index from the set of bit indices to be shortened is ignored. A codeword is generated from all of the remaining output bits.

    Abstract: Millimeter-wave (mmWave) and sub-mmWave technology, apparatuses, and methods that relate to transceivers and receivers for wireless communications are described. The various aspects include an apparatus of a communication device including one or more antennas configured to receive an RF signal and an ADC system. The ADC system includes a 1-bit ADC configured to receive the RF signal, and an ADC controller circuitry configured to measure a number of positive samples in the received RF signal for a plurality of thresholds of the 1-bit ADC, estimate receive signal power associated with the received RF signal based on the measured number of positive samples, determine a direct current(DC) offset in the received RF signal using the estimated received signal power, and adjust the received RF signal based on the determined DC offset.
