A Channel Engineering Method for Future Wireless Communication

Finding inventive and/or innovative ways to enhance the quality of wireless communication by altering the wireless channel is in the cutting edge of modern wireless communication research. Some looks in to ways to introduce foreign objects like "reflective surfaces" to manipulate the wireless environment. Deviating from this line of research, in this paper, a receiver architecture with a "feedback control loop" exploiting a "L�neburg lens " and a dipole antenna array (but with a single RF chain) is proposed and studied. The proposed method iteratively modifies the relative permittivities of the antenna elements in order to alter the effect of gains and phase differences of different multipath components, thus enhancing the quality of wireless communication.
