勒让德多项式的拟合，包括对新的数值的求解(Legendre polynomial fitting, including the new value of solving)

1280点fft变换，改变传统的需2046点FFT的情况。(1280 point FFT，radix 4 and radix 5 )

this is for demo in matlab

通过对RSSI测距模型进行分析， 并提出一种针对室内环境的参数修正方案。 通过 自行研发的传感器节点，上进行验证分析，实验表明，采用环境参数修正方案后， 明显提高了测距的精度。(We studied andanalyzed RSSI—based distance estimated model, and provide aparameter calibration method which in specific to indoor environmental applications．Experience on our prototype node)

说明：  利用MATLAB编写的GUI，可实现串口的通讯和实时画图，有意义(The use of MATLAB written GUI, enables serial communication and real-time drawing meaningful)

i am very tired to describe this is a surprise

MATLAB代码，由于画图，可以直接画出两个或多个数据的线性对比图(MATLAB code, because the drawing, can direct picture out two or more data linear contrast figure )

说明：  6RPS工作空间绘制求解matlab程序(6rps workspace solution)
