Software-defined radios (SDRs) have been around for more than a decade. The first complete Global Positioning System (GPS) implementation was described by Dennis Akos in 1997. Since then several research groups have presented their contributions.We therefore find it timely to publish an up-to-date text on the subject and at the same time include Galileo, the forthcoming European satellitebased navigation system. Both GPS and Galileo belong to the category of Global Navigation Satellite Systems (GNSS).

基于D-J阈值的加性白噪声方差估计,两种算法的比较(D-J，noise,evaluation)

该文件能够实现盲信号的分离，分离效果很好，输入为两种信号的非线性叠加，经过仿真效果很明显！(The document can achieve blind signal separation, separation a good effect, input non-linear superposition of two kinds of signals, through simulation effect is obvious!)
