The ever growing need for higher capacity in wireless systems has fueled the interest in exploiting the spatial dimension-through the use of antennas arrays-to improve the utilization of the available radio spectrum. As a result, a large number of space-time techniques have been proposed wherein arrays are used to mitigate interference and enhance signal levels. More recently, information theory has shown that, with spatial data multiplexing, very large spectral efficiencies can be attained in…

Suppressing opposite-direction interference in TDD/CDMA systems with asymmetric traffic by antenna beamforming
TLDR
This paper compares the uplink bit energy-to-interference density ratio of a traditional beam-steering technique with that of the minimum-variance distortionless-response (MVDR) beamformer, and finds that Scheme IV outperforms all the other three schemes, which can effectively suppress the strong opposite-direction interference in TDD/CDMA systems.
