This project presents a complete end-to-end implementation of Quadrature Phase Shift Keying (QPSK) — a digital modulation technique used in real-world communication systems such as satellite, Wi-Fi, ...
This project details the design and simulation of a 100 kHz Quadrature Down-Converter (QDC). High-frequency Radio Frequency (RF) signals are difficult for standard circuit components to process ...
Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...
Abstract: Affine frequency division multiplexing (AFDM) is an emerging multicarrier technique utilizing chirp signals, specifically designed for high-mobility communication scenarios, and it can ...
The distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...
Abstract: This article proposes a method for generating quadrature self-mixing interference (SMI) signals using the current modulation for real-time displacement sensing. By applying a square-wave ...
Multiple-input multiple-output (MIMO) generalised spatial modulation (GSM) systems represent a pivotal advancement in wireless communication technology. These systems ...
