Latest Patents

One of Cova's latest patents is the Dynamic Digital Pre-Distortion (DDPD) system. This system is designed to rapidly correct power amplifier (PA) non-linearity and memory effects. The DDPD engine predistorts an input signal to cancel PA nonlinearities as the signal is amplified. It is implemented as a composite of one linear filter and N−1 high order term linear filters. The bank of linear filters features programmable complex coefficients. To compute these coefficients, samples from both the transmit path and a feedback path are captured. Covariance matrices A and B are computed using optimized hardware. After this, Gaussian elimination processing is employed to determine the coefficients. Mathematical and hardware optimizations are utilized to simplify and reduce the number of multiplication operands and other operations, allowing the DDPD system to fit within a single chip.
