Butterworth-filter

butterworth低通滤波器的原程序，可用ＭＡＴＬＡＢ的ＦＩＬＴＥＲ函数测试．可得到低通滤波器数字系统函数的系数．(Butterworth low-pass filter the original procedure, MATLAB can be used to test the FILTER function. Available to low-pass filter function of the coefficient of digital systems.)

本程序先使用RSSI中对数常态模型来测距离，然后用三边测量法来计算未知节点的坐标。(The program first uses RSSI in lognormal model to measure the distance, and then use trilateration to calculate the coordinates of the unknown node.)
