Abstract :
A simplified architecture for I/Q digital imbalance compensation of quadrature receiver is presented. The new architecture is obtained by modifying the optimisation criteria of the adaptive decorrelative method. By reducing the number of multipliers, the proposed architecture increases the efficiency of hardware realisations of the digital front end.
