Pulse Code Modulation (PCM), Theory and Matlab code Pulse Code Modulation (PCM) is a method of digitally representing an analog signal. In PCM, the analog signal is sampled at regular intervals, and the amplitude of the signal at each sample…

Quadrature Phase Shift Keying (QPSK) is a type of phase shift keying (PSK) in which two bits of data are encoded in each symbol, allowing for higher data rates than simpler modulation schemes like binary phase shift keying (BPSK). In…

Differential Phase Shift Keying (DPSK) is a type of phase modulation in which the phase of a carrier signal is changed based on the data being transmitted. In DPSK, the phase of the carrier signal is shifted by 180 degrees…

Introduction BPSK stands for Binary Phase Shift Keying. It is a type of digital modulation technique used in digital communications. In BPSK, the phase of a carrier signal is changed to represent two different binary digits or symbols (0 or…
