PLENARY 1: Single Antenna MIMO Transceivers: A New Challenge for Signal Processing

New kinds of MIMO transceivers are explored which are composed of only a single dip antenna surrounded by parasitic elements in close vicinity (can be much closer than wavelength). Steering the conductivity of these parasitic elements within fractions of a symbol duration and oversamping the reeived signal at the dipole at an appropriate rate, a similar effect as with a multi-element MIMO antenna can be achieved. This reduction in physical size achieved at the expense of some drawbacks with respect to complexity of the required signal processing, power efficiency and resistance to adjacent channel interference.
