Abstract
For the known-parameter or full-parameter Gaussian mean-shift sensing model, this letter derives finite-block Ziv–Zakai (ZZB) and Weiss–Weinstein (WWB) bounds for multiple-input multiple-output integrated sensing and communications. Averaging the observed random Gaussian waveform yields deterministic determinant kernels and a complete WWB. At fixed blocklength and increasing signal-to-noise ratio (SNR), the scalar local ZZB approaches the waveform-averaged inverse Fisher information. Its high-SNR relative gap from the inverse mean information vanishes with blocklength. Simulations compare both bounds with estimators, include two ordered targets, and pair finite-block sensing bounds with asymptotic rate.
This work revisits the Gray-Wyner problem of lossy compression of bivariate Gaussian sources under the quadratic distortion measure and derives a covariance shell covering lemma that is analogous to the type covering lemma for the discrete case and derives a achievability proof.
Cell-free massive multiple-input multiple-output is a promising distributed architecture for future wireless networks, where accurate signal-to-interference-plus-noise ratio modeling is essential for channel-parameter inference. This letter proposes a distribution-driven estimator for downlink power-weighted regularize...
This letter derives the closed-form equivalent Fisher information matrix (EFIM) for single-source wideband DOA estimation with a uniform linear array in the presence of unknown sensor phase errors. Based on a deterministic frequency-domain model, the source coefficients are first concentrated out, and the phase-error n...

In this paper, we propose a Zadoff-Chu (ZC) sequence-based pilot design for fractional channel estimation in orthogonal time frequency space (OTFS) modulation for point-to-point multi-input multi-output (MIMO) scenarios. Orthogonal pilot sequences are assigned to each transmit antenna using ZF sequences. At the receive...

Approximate Message Passing (AMP) algorithms are attractive as they are computationally efficient and simultaneously admit a precise characterization in terms of the low-dimensional"state-evolution"recursion. In this work, we establish quantitative universality for AMP with centered rank-one sensing matrices $Z_i=(x_ix...

Probabilistic shaping (PS) is a well-known method to achieve improved performance upon a regular quadrature amplitude modulation (QAM) by taking the target constellation and making the distribution of underlying points non-uniform. It has been extensively studied over the years for the additive white Gaussian noise (AW...
