Performance of a non-orthogonal STBC over correlative fading channels [PDF]
It has been recently shown that, for non-orthogonal space-time block code (STBC), the multiple-input multiple-output (MIMO) maximum-likelihood (ML) metric can also be decoupled into single-input single-output (SISO) ML metrics for decoding simplification

Abstract Climate change is increasing global atmospheric temperatures, which can reduce abundance and cause range shifts in species that are sensitive to warming. However, fine‐scale thermal heterogeneity can drive highly variable local responses to climate change, especially in freshwater environments that differ in groundwater inputs and ...

STBCs from Representation of Extended Clifford Algebras [PDF]
A set of sufficient conditions to construct $λ$-real symbol Maximum Likelihood (ML) decodable STBCs have recently been provided by Karmakar et al. STBCs satisfying these sufficient conditions were named as Clifford Unitary Weight (CUW) codes. In this paper, the maximal rate (as measured in complex symbols per channel use) of CUW codes for $λ=2^a,a\in ...

Summary The emergence of new pathogens is an ongoing threat to human health and agriculture. While zoonotic spillovers received considerable attention, the emergence of crop diseases is less well studied. Here, we identify genomic factors associated with the emergence of Pseudomonas syringae bacterial blight of coffee. Fifty‐three P.

Upper Bounds on the BER Performance of MTCM-STBC Schemes over Shadowed Rician Fading Channels
Space-time block coding (STBC) provides substantial diversity advantages with a low decoding complexity. However, these codes are not designed to achieve coding gains. Outer codes should be concatenated with STBC to provide additional coding gain.

Unitary Nongroup STBC From Cyclic Algebras [PDF]
Space-time block codes (STBCs) are designed for multiple-input-multiple-output (MIMO) channels. In order to avoid errors, single-input-single-output (SISO) fading channels require long coding blocks and interleavers that result in high delays. If one wishes to increase the data rate it is necessary to take advantage of space diversity. Early STBC, that
