function?[]?=?Channel_Gain（Cell_NumberUE_Coords_xUE_Coords_yEnodeBs）
%函數功能：建立小區拓撲圖，計算給定坐標點與所選基站間的信道增益
%參數說明：
%Input?args
%Cell_Number:需要建立拓撲的邊長，實際畫出Cell_Number^2個小區
%UE_Coords_x:UE橫坐標
%UE_Coords_y:UE縱坐標
%EnodeBs：所選小區序號
%Output?args
%Distance:輸入坐標與選定小區基站間距離
%H:信道增益
%%?Create?EnodeBs
theta?=?linspace（02*pi7）;?%產生從0~2*pi的7點矢量，將360度6等分成每個60°
r=1;????%小區半徑為1
Bs_Location=zeros（12Cell_Number^2）;%建立基站坐標矩陣
