WebGaussian (CSCG) vector with mean vector x and covariance matrix Σ is denoted by CN(x,Σ), and ∼ means “distributed as”. E{·} denotes statistical expectation. II. SYSTEM MODEL A. Channel Model We focus on a frequency flat slow fading channel for downlink multiuser SWIPT systems, cf. Figure 1. In particular, WebSep 18, 2024 · This paper considers an amplify-and-forward two-way relay system with frequency selective fading channels. The knowledge of channel state information is assumed not available for all nodes. An efficient transmission and signaling scheme is proposed to identify the transmitted symbols and multi-tap channel coefficients using the …

WebMar 26, 2024 · For our proposed AoAs estimation algorithm, we firstly obtain the ordered detection probability output vector through periodic beam scanning at the BS after sorting in descending order as p ^ (1), n, ⋯, p ^ (M + 1), n, where p ^ (i), n ⩾ p ^ (i + 1), n, ∀ i. Then we calculate the Wald-type confidence interval which will be used to ...
