According to principles of modulation and demodulation, transmission performance of QAM and QPSK was compared to present an algorithm of adaptive modulation. Testing environment was established to verify that adaptive technique is able to highly enhance transmission rate. Results demonstrate that TETRA II product could meet transmission requirements of mainstream data, such as image and low-resolution video.
