Implementing BPSK Modulation Using Simulink Block Diagrams

This implementation demonstrates Binary Phase Shift Keying (BPSK) modulation using Simulink simulation block diagrams. The block diagram showcases key components including signal sources, modulators, and communication channels. The signal source generates binary data sequences, which are then processed by the modulator for phase shifting operations. The modulated signal is transmitted through the communication channel to the receiver end.

From an implementation perspective, Simulink provides built-in blocks such as the Bernoulli Binary Generator for signal generation and the BPSK Modulator Baseband block for phase modulation. The modulation process typically involves mapping binary '0' to 0° phase shift and binary '1' to 180° phase shift. Key parameters like carrier frequency, symbol rate, and filter specifications can be configured through block parameter dialogs. The simulation allows for real-time observation of signal waveforms, constellation diagrams, and bit error rate analysis, providing comprehensive insights into BPSK modulation principles and communication system performance.
