BPSK, QPSK, and QAM16 Modulation and Demodulation

This text provides a detailed introduction to BPSK, QPSK, and QAM16 modulation and demodulation techniques along with their implementation in MATLAB. These modulation schemes are fundamental methods widely used in wireless communications, making them particularly suitable for beginners. Through MATLAB simulations, we can better understand the principles and applications of these modulation techniques. The implementation typically involves key functions such as pskmod() and pskdemod() for PSK schemes, and qammod() and qamdemod() for QAM modulation in MATLAB's Communications Toolbox. Additionally, we can explore common Bit Error Rate (BER) performance analysis methods and demonstrate how to evaluate different modulation schemes using MATLAB's berawgn() function for theoretical BER calculations and monte carlo simulations for practical performance evaluation. By deeply studying these concepts with hands-on code examples, beginners can effectively master BPSK, QPSK, and QAM16 modulation and demodulation techniques.
