EficientQAMmodulationsystemofsoftwaredefinedradiop
在分析高效宽频带变频系统的基础上提出一种可以把变频部分与多种调制方式灵活结合在一起的方法，并以QAM调制为例，给出具体算法．分析结果表明，该方法降低了对处理速率的要求，提高了处理能力(In order to design an efficient and flexible DDC／DUC system，this paper combined the signal processing of DDC／DUC with QAM system and presented a new method based on the analysis of this efficient broadband DDC／DUC system．QAM modulation was taken for example，and a detailed algorithm of a channel system with 0～30 MHz and 60 channels QAM was presented)

QPSK在加性高斯白噪声环境下，信噪比和误码率的仿真。
先产生一个四组符号的序列，再将该序列映射到对应的相位上。用相应的函数产生均值为零、方差为δ2的加性高斯噪声。
(QPSK the additive white Gaussian noise environment, and the signal-to-noise ratio of the simulation. First group have a four symbols of sequence, then this sequence mapped to the corresponding phase on. With the corresponding function have zero mean and variance of 未2 additive white Gaussian noise.)
