Abstract: A system and method are provided in which an input including a measurement output of digital channel information is received. The digital channel information includes an estimated digital channel, a beamforming codebook, and quantized angle of arrival (AoA) values. A basis corresponding to one of the quantized AoA values is selected according to a largest projection power of the measurement output. A partial channel is recovered based on the beamforming codebook and the estimated digital channel. An analog channel is recovered based on the partial channel and the basis.

Abstract: A method of pre-compensating for transmitter in-phase (I) and quadrature (Q) mismatch (IQMM) may include sending a signal through an up-converter of a transmit path to provide an up-converted signal, determining the up-converted signal, determining one or more IQMM parameters for the transmit path based on the determined up-converted signal, and determining one or more pre-compensation parameters for the transmit path based on the one or more IQMM parameters for the transmit path. In some embodiments, the up-converted signal may be determined through a receive feedback path. In some embodiments, the up-converted signal may be determined through an envelope detector.

Abstract: A system, method, and electronic device for compensating in-phase (I) and quadrature (Q) mismatch (IQMM) are herein disclosed. The system includes an IQ mismatch compensator (IQMC) configured to compensate for IQMM between a time-domain I signal and a time-domain Q signal using filter weight coefficients, and output a compensated I signal and a compensated Q signal, a fast Fourier transformation (FFT) circuit configured to perform an FFT on the compensated I signal and the compensated Q signal to a frequency-domain compensated signal, and a coefficient updater configured to update the filter weight coefficients based on a frequency-domain observation of the frequency-domain compensated signal.

Abstract: A method of compensating for IQ mismatch (IQMM) in a transceiver may include sending first and second signals from a transmit path through a loopback path, using a phase shifter to introduce a phase shift in at least one of the first and second signals, to obtain first and second signals received by a receive path, using the first and second signals received by the receive path to obtain joint estimates of transmit and receive IQMM, at least in part, by estimating the phase shift, and compensating for IQMM using the estimates of IQMM. Using the first and second signals received by the receive path to obtain estimates of the IQMM may include processing the first and second signals received by the receive path as a function of one or more frequency-dependent IQMM parameters.

Abstract: A method and system for training a neural network are herein provided. According to one embodiment, a method includes generating a first labelled dataset corresponding to a first modulation scheme and a second labelled dataset corresponding to a second modulation scheme, determining a first gradient of a cost function between a first neural network layer and a second neural network layer based on back-propagation using the first labelled dataset and the second labelled dataset, and determining a second gradient of the cost function between the second neural network layer and a first set of nodes of a third neural network layer based on back- propagation using the first labelled dataset. The first set of nodes of the third neural network layer correspond to a first plurality of detector classes associated with the first modulation scheme.

Abstract: An apparatus and a method are provided in which a processor of a receiving apparatus regenerates time domain samples of an interfering data numerology from frequency domain received signals. The processor performs pre-fast Fourier transform (FFT) processing of a desired data numerology on the regenerated time domain samples of the interfering data numerology. The processor performs FFT, with a size corresponding to the desired data numerology, on the regenerated time domain samples after performing pre-FFT processing to generate an interfering numerology cancelation signal. The processor subtracts the interfering numerology cancelation signal from a frequency domain received signal of the desired data numerology to reduce an effect of interference of the interfering data numerology on the desired data numerology.
