“…By nature, the channel is stochastic, which motivates Bayesian estimation-that is, modeling of the current channel state as a realization from a known multi-variate probability density function (PDF). There is also a large amount of literature on estimation of deterministic MIMO channels which are analytically tractable but in general provide less accurate channel estimates, as shown in [7], [8]. Herein, we concentrate on minimum mean square error (MMSE) estimation of the channel matrix and its squared Frobenius norm, given the first and second order system statistics.…”

“…Figure 3 also shows (dashed lines) that operating flashy scheme below the transition point can maintain the bit energy equal to its minimum. From Figure 3, we can also see that the dashdotted line plotted without spatial correlation (T c = 20) is above the real line of T c = 20 for about ¶ Generally, R t is not of low rank algebraically but with small eigenvalues decaying quickly [24]. Here for clarifying our results, we construct a rank-deficient R t algebraically by neglecting some small zero-approaching eigenvalues.…”

“…In addition from (24) and for fixed N r , E r b /N 0 | →0 ∝ K 2 t /N t . It is not clear whether the value of K 2 t /N t will increase or decrease with N t , which depends on the concrete settings (such as spatial correlation and antenna aperture).…”
