Latest Patents

Ganesan Raghu holds a patent titled "Blind I/Q mismatch compensation with receiver non-linearity." This invention provides apparatus and methods that perform gain, clipping, and phase compensation in the presence of I/Q mismatch in quadrature RF receivers. The patent addresses the issues of gain and phase mismatch, which are exacerbated by differences in clipping between I and Q signals in low-resolution analog-to-digital converters (ADCs). The invention ensures that signals in the stronger channel arm are clipped differentially more than weaker signals in the other channel arm. By performing clipping operations during iterations of gain mismatch calculations, the invention balances clipping between the I and Q channel arms. Gain compensation coefficients are iteratively converged, clipping levels are established, and data flowing through the network is gain and clipping compensated. A compensation phase angle and phase compensation coefficients are then determined from the gain and clipping compensated sample data. The resulting phase compensation coefficients are applied to the gain and clipping corrected receiver data to yield a gain, clipping, and phase compensated data stream.
