Adaptive modulation can improve both the energy and spectral efficiency. In this paper, the performance analysis of BER and BPS based on adaptive modulation between BPSK, QPSK, 16QAM and 64QAM are given. Simulation shows that the result of adaptive modulation are better than that of fixed modulation.
