An error event sensitive trade-off between rate and coding gain in MIMO MAC
Toni Ernvall, Jyrki Lahtonen, Hsiao-feng +2
This work considers space-time block coding for the Rayleigh fading multiple-input multiple-output (MIMO) multiple access channel (MAC). If we suppose that the receiver is performi…
Remarks on the Criteria of Constructing MIMO-MAC DMT Optimal Codes
Hsiao-feng, Lu, Jyrki Lahtonen +2
In this paper we investigate the criteria proposed by Coronel et al. for constructing MIMO MAC-DMT optimal codes over several classes of fading channels. We first give a counterexa…
On the Decay of the Determinants of Multiuser MIMO Lattice Codes
Jyrki Lahtonen, Roope Vehkalahti, Hsiao-feng Lu +2
In a recent work, Coronel et al. initiated the study of the relation between the diversity-multiplexing tradeoff (DMT) performance of a multiuser multiple-input multiple-output (MU…
Maximal Orders in the Design of Dense Space-Time Lattice Codes
Camilla Hollanti, Jyrki Lahtonen, Hsiao-feng Francis Lu
We construct explicit rate-one, full-diversity, geometrically dense matrix lattices with large, non-vanishing determinants (NVD) for four transmit antenna multiple-input single-out…
On the densest MIMO lattices from cyclic division algebras
C. Hollanti, J. Lahtonen, K. Ranto +1
It is shown why the discriminant of a maximal order within a cyclic division algebra must be minimized in order to get the densest possible matrix lattices with a prescribed nonvan…
