Digital precompensation of imperfections in quadrature modulators.

Digital precompensation of imperfections in quadrature modulators.

Residual carrier, balance, and quadrature error imperfections that are normally present in phase/quadrature modulators limit the use of direct modulation techniques in some applications. The classical precompensation techniques are revised and an adaptive solution proposed that improves performance...
