4-πdqpsk的labview虚拟设计，提供了不同滤波器阶数及脉冲成型模块，是值得学习的好材料-4-πdqpsk the labview virtual design, provides a different filter order and pulse shaping module, is worth a good learning materials

在matlab上仿真QPSK BPSK过成型滤波器，AWGN信道，上下变频后的误码率情况-On the matlab simulation QPSK BPSK been shaping filter, AWGN channel, the error rate down conversion after the case

利用 LABVIEW 和 NI USRP 数字通信实验平台，实践 4-QAM 数字调制器和脉冲成型滤波器的原型设计和性能评测。 USRP需自己提供。(The prototype design and performance evaluation of 4-QAM digital modulator and pulse shaping filter are implemented on the experimental platform of LABVIEW and NI USRP digital
