Abstract :
An adaptive I/Q regeneration technique for direct receivers is presented. The technique is based on the property that I/Q components of quadrature-modulated signals are uncorrelated, and its implementation involves a second order LMS algorithm. Simulations are performed with the SPW and results show that its performance matches the theory.
