Energy-Efficient Signal Detectors For Massive MIMO Using SRAM-Based IMCs
A new technical paper titled “Energy-Accuracy Trade-Offs in Massive MIMO Signal Detection Using SRAM-Based In-Memory Computing” was published by researchers at the University of Illinois at Urbana–Champaign. Abstract “This paper investigates the use of SRAM-based in-memory…
Note: “This paper investigates the use of SRAM-based in-memory computing (IMC) architectures for designing energy efficient and accurate signal detectors for massive multi-input multi-output (MIMO) systems. SRAM-based IMCs are the state-of-the-art for executing deep learning workloads in terms of energy efficiency and compute density. However, given the more stringent accuracy requirements of massive…
Exploring the Relationship Between FM Wave Bandwidth and the Modulation Index
In this article, we'll investigate how varying the amplitude and frequency of the modulating tone impacts the bandwidth of FM signals. We'll also compare the modulation index in AM and FM schemes.
Exploring Bessel Functions: Understanding the Spectrum of Tone-Modulated FM
In this article, we’ll learn about the essential properties of Bessel functions and what they can tell us about the bandwidth of practical FM signals.
the spectrum of FM waves generated by a single-frequency message signal consists of an infinite number of sidebands
Jn(β). This scaling factor is known as the Bessel function of the first kind.
Introduction to Wideband FM Signals
Learn how Bessel functions and the modulation index can help us understand the bandwidth of wideband frequency-modulated (FM) signals.
