  • Time-domain IQ mismatch compensator with frequency-domain observations
    Patent number: 10749555
    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.
    Type: Grant

  • Apparatus configured to approximate a power coefficient in a cell-free massive MIMO wireless system and method of performing same
    Patent number: 9918317
    Abstract: A central node may include a processor configured to empirically compute an approximation of power coefficients based on estimates of the channel coefficients such that a same one of the approximation of the power coefficient is assigned to each of a plurality of access terminals (ATs), and transmit components of a signal vector to associated access points (APs), the signal vector being based on at least the approximation of the power coefficient.
