Digital Signals: QPSK, BPSK, and MSK Explained
Demystifying Digital Modulation: QPSK, BPSK, and MSK In the ever-evolving world of communication, data needs to travel efficiently and reliably. This is where digital modulation techniques come into play, transforming digital information into a format suitable for transmission over various mediums like radio waves or optical fibers. This blog post delves into three popular modulation techniques: Quadrature Phase-Shift Keying (QPSK), Binary Phase-Shift Keying (BPSK), and Minimum Shift Keying (MSK). Understanding these techniques unlocks the secrets behind how your data travels seamlessly across the digital landscape. 1. BPSK: The Foundation of Digital Modulation Binary Phase-Shift Keying (BPSK) is the simplest form of digital modulation, often considered the foundation for more complex techniques. In BPSK, a binary signal (0 or 1) is...
