Abstract

MIMO techniques exploit multipath signals from all directions. Unfortunately, this means that all the antennas can be jammed by a single co-channel blocker from any direction. Linear filtering techniques, that have an inverse, can be used to provide RF beamforming when combined with a baseband inverse without losing any of the multipath information. An example of such a filter includes the FFT/IFFT combination, shown in Fig. 6.4.1. Prior techniques have attempted to solve the MIMO co-channel blocker problem by providing nulls in individual directions [1]. These techniques provide finite jammer rejection in only one spatial direction. These have been extended to handle multiple spatial blockers [2]-[4]. However, all these techniques use active circuits for spatial filtering, which limits the ability to handle co-channel interference.
