資源簡介
本程序是實現基于UWB的節點位置進行定位及對算法仿真，采用基于到達時間TOA
算法仿真了UWB信號在IEEE802.15.4a信道下的發射、衰減、信道沖擊響應、加噪聲
相關接收、節點定位；參考節點個數選擇為3個，定位坐標采用最小二乘法求解
The algorithm simulates the transmission, attenuation, channel impulse response and noise of UWB signal in ieee 802.15.4a channel
Relevant reception and node positioning;The number of reference nodes is 3, and the positioning coordinates are solved by the least square method)

function?y=biggestprobility（xprecision）
%?x=[6.9952????6.9952????6.9952????6.9952????7.5281????6.9952????6.9952????7.0285????6.9952????6.9952]
%?precision=0
%只取在某個范圍內分步最多的那些數的平均值。
%1、將x按照精度precision進行四舍五入存放到a中；2、所有的x按照精度劃分為若干個組groupvalue并統計各個組的樣本的個數groupcount；3、取出樣本個數最多的那個組的值t;4、將對應的原始數據x放到valid中，最后求valid的平均值。
