This paper presents our initial investigations of noise enhancement control when decoding uplink transmissions in multi-cell multiuser multiple- input multiple-output (MU-MIMO) systems with zero- forcing (ZF) post-processing. This problem has been partially addressed within simplified cellular system topologies and with single antenna terminals. However, applying existing solutions directly to a multi...
This paper considers an interference-aware user selection and resource allocation for uplink multiuser multiple-input multiple-output (MU-MIMO) systems. At the base station (BS), zero-forcing (ZF) with singular value decomposition (SVD) decoupling of spatial streams is deployed. First, two algorithms are developed for mobile stations (MS)s and their corresponding antennas assignment as well as power...
This paper introduces a low complexity postprocessing technique allocating spatial streams for uplink transmissions in multiuser (MU) multiple-input multiple-output (MIMO) systems. The scheme is based on zero-forcing (ZF) cancelation of the multiple access interference (MAI) caused by simultaneous transmissions to the access point (AP) equipped with multiple receive antennas from selected users equipped...
