Abstract	In this paper, two adaptive-antenna based schemes for interference suppression are proposed. In the rst approach, referred to as Matched Desired Impulse Receiver (MDIR), a narrowband beamformer aiming to cancel out interferers is placed prior to the single-user data detection stage. In contrast, intracell users are jointly detected in the multi-sensor JD-MMSE (Joint Detection with MMSE criterion) algorithm. For this latter scheme, lower complexity versions are derived on the assumption that noise plus interference is white in the temporal domain. In order to assess performance vs. complexity trade-o s, a set of link-level computer simulations adopting the UTRA-TDD air-interface is provided. Simulation results re ect signi cant gains with respect to the single-sensor counterparts of the aforementioned schemes. On the other hand, despite that superior results were obtained with the JD-MMSE approach, the MDIR algorithm constitutes an appealing recon gurable and lower-complexity alternative. 1.
