Subchannel Allocation in Multiuser Multiple-Input–Multiple-Output Systems
TL;DR: Simulation results show that a novel suboptimum zero-forcing allocation strategy that directly results in a set of virtually decoupled scalar channels tightly approaches the performance of the optimum solution, i.e., complexity reduction comes at almost no cost in terms of sum capacity.
Journal ArticleDOI
Rate Balancing in Multiuser MIMO OFDM Systems
TL;DR: A suboptimum non-iterative algorithm is introduced that does not require time-sharing and very closely approaches the optimum solution of the optimum iterative approach for general MIMO channels.
Proceedings ArticleDOI
Multiuser MIMO Channel Measurements and Performance in a Large Office Environment
Gerhard Bauch,J. Bach Andersen,Christian Guthy,Markus Herdin,Jesper Ødum Nielsen,Josef A. Nossek,Pedro Tejera,Wolfgang Utschick +7 more
TL;DR: The evaluation and explanation of multiuser MIMO in a real world scenario, i.e. a large office room, based on measured channels is evaluated and the theoretical limits can be approximately achieved.
Proceedings ArticleDOI
Efficient linear successive allocation for the MIMO broadcast channel
TL;DR: An efficient linear zero-forcing algorithm for this problem, which is derived from maximizing a lower bound for the sum rate, successively allocates data streams to users and in contrast to state of the art approaches thereby also determines the corresponding receive filters.
Proceedings ArticleDOI
Joint bit and power loading for MIMO OFDM based on partial channel knowledge
TL;DR: A method for bit and power loading is presented that based on the notion of pairwise error probability (PEP) leads to an optimum distribution of bits and power for a given transmit power and spectral efficiency in an OFDM context.
