Consider a training-based communication system with data power ratio $\alpha$ and effective signal-to-noise ratio $\rho_{\rm eff}$. Let $\alpha_\star$ be the power allocation that…

Let $\rho_{\text{eff}}$ denote the effective signal-to-noise ratio, and let $\widetilde{\rm{MSE}}_{\text{\tiny{Box-RLS}}}$ and $\widetilde{\rm{SEP}}_{\text{\tiny{Box-RLS}}}$ denote…

The GEC-C detector is a proposed MIMO detector based on Bayesian inference, and Bayesian MMSE performance refers to the minimum mean-square error achievable under the Bayesian mode…

Gaussian belief propagation is considered for the pair-wise graph rules 2G and 3G. The Gaussian BP mean-convergence conjecture. For both the Gaussian BP of rules 2G and 3G, the mea…

Let $\hat{\mathbf{s}}$, $\hat{\mathbf{s}}_M$, or $\hat{\mathbf{s}}_{\epsilon}$ be approximated by divided decoding with sphere decoding according to a splitting index set…

Let $M$-QAM denote a quadrature-amplitude-modulation signal set with constellation size parameter $M$. Consider the large-MIMO-system limit for the LAS detector and the maximum-lik…
