Abstract

The paper deals with the principle of 16QAM modulation and demodulation of high data rate-to-bandwidth ratio, and the BER in the transmission of 16QAM modulation BPSK modulation and QPSK modulation was compared with simulation by MATLAB. The experiment proves that 16QAM modulation and demodulation is not only easy to achieve but also better to perform.
