BPSK Modulation Matlab Simulation Source Code

In this article, we explore BPSK (Binary Phase Shift Keying) modulation and provide Matlab simulation source code. BPSK is a fundamental digital modulation technique widely employed in communication systems. Through Matlab simulation, we can effectively analyze and understand BPSK modulation performance characteristics. The subsequent sections detail how to implement BPSK modulation simulation code in Matlab, including key algorithmic components such as bit-to-symbol mapping, carrier modulation, and constellation diagram generation. We demonstrate practical approaches for generating random binary data, applying phase shift modulation using cosine functions, and evaluating system performance through BER (Bit Error Rate) calculations. The implementation utilizes core Matlab functions including randi() for data generation, cos() for carrier modulation, and scatterplot() for constellation visualization. Additional analysis covers AWGN channel modeling using awgn() function and demodulation techniques employing phase comparison algorithms.
