摘要
移动通信的物理层采用的调制方式主要有BPSK、QPSK、16PSK、16QAM等自适应数字调制解调技术。本文通过对信源产生的数字信号，经过16QAM调制解调方式对信号进行调制。通过对误码率的测试比较，来分析16QAM调制解调方式的性能。
Adaptive modulation technique is hot field of mobile communications in recent years communications physical layer modulation used adaptive digital modulation and demodulation technology 16PSK, 16QAM. In this thesis, source of digital signals generated through 16QAM and demodulation of Through bit error rate of the test compared to analyze a variety of modulation and demodulation.
