This paper considers the selection of users and corresponding uplink decoding in multi-user multiple-input multiple-output (MU-MIMO) multi-cell systems, applicable to future wireless networks with centralized processing at the wireless controller (...
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...
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...
Cooperative communications is a new wireless networking paradigm that allows networking nodes to collaborate through distributed transmission and signal processing to implement spatial and time signal diversity to combat the effects of fading...
Internet became one of life’s basics in these days. More networks are connected to the Internet every day, which increases the amount of valuable data and the number of resources that can be attacked. Some systems have been designed and developed to...
This paper is concerned with the power allocation problem in a transmit diversity wireless system with mean channel gain information. For a given set of mean channel gains between nodes, the aim is to find the power allocation and corresponding...
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...
This dissertation investigates cross-layer designs in spatial division multiplexing (SDM) for multiuser multiple-input multiple-output (MU-MIMO) transmissions on the uplink. The MU systems which allow simultaneous transmissions on the downlink offer...
