Developed by a team led by Matt Ettus, the USRP product family is intended to be a comparatively inexpensive hardware platform for software radio, and is commonly used by research labs, universities, and hobbyists.[1])

由sp3精密星历，得到关于GPS接收机的精确位置(get the exact position of the GPS receiver)

To invert a square Galois array, use the inv function. Related is the det function, which computes the determinant of a Galois array. (To invert a square Galois array, use the inv function. Related is the det function, which computes the determinant of a Galois array.)

设有连续时间周期信号，它的周期为T，角频率，且满足狄里赫利条件，则该周期信号可以展开成傅里叶级数，即可表示为一系列不同频率的正弦或复指数信号之和。(With continuous time periodic signal, its period is T, the angular frequency, and to meet the Diliheli conditions, the periodic signal can be expanded into a Fourier series, can be expressed as a range of different frequencies of sinusoidal or complex exponential signal and.)
