The Discrete Cosine Transform and Its Impact on Visual Compression: Fifty Years From Its Invention [Perspectives] IEEE Signal Proc. Mag. (IF 14.9) Pub Date : 2023-09-07 Yao Wang, Debargha Mukherjee
Compression is essential for efficient storage and transmission of signals. One powerful method for compression is through the application of orthogonal transforms, which convert a group of ${N}$ data samples into a group of ${N}$ transform coefficients. In transform coding, the ${N}$ samples are first transformed, and then the coefficients are individually quantized and entropy coded into binary bits

Integrated Sensing and Communications With Reconfigurable Intelligent Surfaces: From signal modeling to processing IEEE Signal Proc. Mag. (IF 14.9) Pub Date : 2023-09-07 Sundeep Prabhakar Chepuri, Nir Shlezinger, Fan Liu, George C. Alexandropoulos, Stefano Buzzi, Yonina C. Eldar
Integrated sensing and communications (ISAC) are envisioned to be an integral part of future wireless networks, especially when operating at the millimeter-wave (mm-wave) and terahertz (THz) frequency bands. However, establishing wireless connections at these high frequencies is quite challenging, mainly due to the penetrating path loss that prevents reliable communication and sensing. Another emerging

Periodograms and the Method of Averaged Periodograms [Lecture Notes] IEEE Signal Proc. Mag. (IF 14.9) Pub Date : 2023-09-07 Shlomo Engelberg
In this “Lecture Notes” column, we show that it is possible to use deterministic arguments to gain some intuition into why using periodograms without averaging does not work well and why they “fail” in the way they do. We then explain how the probabilistic case can be seen as an extension of the deterministic case. Next, we give a brief description of the method of averaged periodograms and explain

Deep Learning Meets Sparse Regularization: A signal processing perspective IEEE Signal Proc. Mag. (IF 14.9) Pub Date : 2023-09-07 Rahul Parhi, Robert D. Nowak
Deep learning (DL) has been wildly successful in practice, and most of the state-of-the-art machine learning methods are based on neural networks (NNs). Lacking, however, is a rigorous mathematical theory that adequately explains the amazing performance of deep NNs (DNNs). In this article, we present a relatively new mathematical framework that provides the beginning of a deeper understanding of DL

Discriminative and Generative Learning for the Linear Estimation of Random Signals [Lecture Notes] IEEE Signal Proc. Mag. (IF 14.9) Pub Date : 2023-09-07 Nir Shlezinger, Tirza Routtenberg
Inference tasks in signal processing are often characterized by the availability of reliable statistical modeling with some missing instance-specific parameters. One conventional approach uses data to estimate these missing parameters and then infers based on the estimated model. Alternatively, data can also be leveraged to directly learn the inference mapping end to end. These approaches for combining

Twenty-five years ago, the field of computational imaging arguably did not exist, at least not as a standalone arena of research activity and technical development. Of course, the idea of using computation to form images had been around for several decades, largely thanks to the development of medical imaging—such as magnetic resonance imaging (MRI) and X-ray tomography—in the 1970s and synthetic-aperture

Contrary to orthogonal multiple-access (OMA), non-orthogonal multiple-access (NOMA) schemes can serve a pool of users without exploiting the scarce frequency or time domain resources. This is useful in meeting the future network requirements (5G and beyond systems), such as, low latency, massive connectivity, users’ fairness, and high spectral efficiency. On the other hand, content caching restricts
