Latest Patents

Brian Reggiannini holds a patent for "Real-time I/Q imbalance correction for wide-band RF receiver." This invention involves a receiver apparatus that models and corrects both frequency-dependent and frequency-independent mismatches between I and Q paths through polynomial estimations. The apparatus samples digitized I and Q path signals, modeling the sampled data points in equations with real and imaginary components. The discrete time-domain data is converted to frequency-domain data, allowing for the computation of multiple statistical values. Coefficients for the polynomial equations are estimated based on these computed statistics, enabling the estimation of channel mismatches. This information is then used to compensate for mismatches on either the I path or the Q path.
