Introduction Quadrature Phase Shift Keying (QPSK) is one of the most commonly used digital modulation schemes due to its efficiency in bandwidth utilization and robustness against noise. It encodes two bits per symbol by shifting the phase of the carrier …
Introduction to Quadrature Modulation Quadrature Phase Shift Keying (QPSK), also known as 4-PSK, is a widely used digital modulation technique that enhances bandwidth efficiency by encoding data into phase variations of a carrier wave. Quadrature modulation reduces the required bandwidth …
