Implementation of SM and RxTxIR on a DSP-Based Wireless MIMO Test-Bed
2004 (English)In: Proceedings of the European DSP Education and Research Symposium EDERS, 2004Conference paper (Refereed)
In this paper we describe the implementation of two smart-antenna strategies and associated signal processing algorithms on a common DSP-based wireless MIMO test-bed. The test-bed supports single cell and two-cell conﬁgurations. All nodes (MS andBS) have two antennas (either two transmit or tworeceive) and there are feedback links (via cable) from the receivers to all transmitters.These possibilities has been utilized differently in the two techniques: spatial multiplexing (SM) and joint receiver transmitter and interference rejection (RxTxIR).The SM technique targets a single-link low-mobility scenario and boosts throughput using two parallel spatially multiplexed modulation streams. The RxTxIR scheme utilizes the two-cell conﬁguration of the testbed to demonstrate the possibility of suppressing intercell interference in transmitter as well as the receiver beamforming.
