Iterative MIMO Detection for Rank-Deficient Systems [PDF]

, 2006
In this letter, a novel iterative multiple-input multiple-output (MIM)O detector reminiscent of sphere decoding (SD) is presented. Its main benefit is that in contrast to other softinput soft-output (SISO) SD algorithms presented in the literature, the ...

Sparse Grassmannian Design for Noncoherent Codes via Schubert Cell Decomposition

IEEE Open Journal of the Communications Society
In this paper, we propose a method for designing sparse Grassmannian codes for noncoherent multiple-input multiple-output systems. Conventional pairwise error probability formulations under uncorrelated Rayleigh fading channels fail to account for rank ...

Fading performance evaluation of a semi-blind space-time equaliser for frequency selective MIMO systems

, 2011
A semi-blind adaptive space–time equaliser (STE) has recently been proposed based on a concurrent gradient-Newton(GN) constant modulus algorithm (CMA) and soft decision-directed (SDD) scheme for dispersive multiple-input multiple-output (MIMO) systems ...

Optical multiple input and multiple output (MIMO) in multimode fibre

, 2013
Recently, there has been a dramatic increase in the amount of data transmission within short range local area networks (LAN). Multimode fibre (MMF) is widely used in local area networks because of its coupling and alignment along with the low cost of related components. Graded index MMF has become common due to the reduction in pulse spreading; however,
