Introduction Welcome to our latest blog post accompanying our YouTube video on DPSK (Differential Phase Shift Keying) Modulation and Demodulation. If you're diving into digital communication, understanding modulation techniques like DPSK is essential. This post will provide an overview of DPSK, explain the experimental setup, and guide you through the results and their significance. What is DPSK? Differential Phase Shift Keying (DPSK) is a modulation scheme where the phase of the carrier signal is modulated relative to the previous symbol. Unlike standard PSK (Phase Shift Keying), DPSK does not require a coherent reference signal at the receiver, making it more robust to phase noise and simplifying the receiver design. Key Advantages of DPSK: No Need for Carrier Recovery: Reduces complexity in the receiver. Better Performance in Phase Noise: More resilient compared to coherent PSK. Experimental Setup In the Trainer Kit experiment, we used a practical approach to demonstrate DPSK ...
