摘　　要：为了同时产生多个调制信号,提出了基带多个调制信号产生方法,并设计配置了AD9361发射链路各模块,包含设置时钟锁相环的3个寄存器和控制频率合成器的7个寄存器。最后,利用Agilent频谱仪及配套软件Agilent89600测量所产生的多16QAM和QPSK信号误差向量幅度EVM等性能指标,各调制信号的EVM可达1.5%左右,与由AgilentE4436B信号发生器产生的单个16QAM信号相当,优于多数传统发射机。In order to generate multiple modulation signals at the same time,firstly a method of generating multiple baseband modulation signals is proposed. Then modules of the AD9361 transmission path are configured which include the clock phase locked loop set by three registers and the frequency synthesizer set by seven registers.At last,multiple 16 QAM and QPSK signals are generated by the proposed method.Their performances are measured with an Agilent spectrum analyzer and supporting with the Agilent89600 software.And their EVM can reach about 1.5%,it is equal of that of a 16 QAM signal which is generated by the AgilentE4436 Bvector signal generator and is significantly better than most traditional transmitters.
