This paper considers the multi-user MIMO collaborative spatial multiplexing uplink scheduling scheme in multi-cell time-division duplexing system. An transmitter centric (TC) beamforming and scheduling scheme has been proposed to reduce the inter-cell interference opportunistically. Most previous works in the area of mimo beamforming and scheduling are aiming at improve the signal to interference...
The exceeding performance of Close-Loop MIMO scheme over Open-Loop one is attractive. However, the large size of Channel State Information (CSI) feedback to transmitter is its major drawback. To reduce this cost, many works have been done on CSI feedback design in frequency domain for MIMO-OFDM systems. We propose a scheme which represents the CSI in temporal domain. Based on that the channel is inherent...
Multiple input multiple output (MIMO) wireless systems have gained increasing attention today. Based on research for the known spatial multiplexing detection algorithms, in order to improve BER performance and decrease the computational complexity, we propose a MIMO transceiver scheme using singular linear transformation (SLT) in this paper. In this scheme, the transmitted signal vectors with a proper...
