Abstract :
An image suppression technique is proposed for superheterodyne receivers. Adopting a dual-antenna structure, two independent signal observations are generated at baseband, containing both the desired and image signals. Independent component analysis (ICA) technique is employed to separate the desired signal from the image signal. The results of computer simulations confirm the effectiveness and robustness of the proposed technique under typical fading conditions. In addition, the algorithm has fast convergence.
