bfsk程序代码matlab

bfsk在高斯信道和锐利多径衰落信道中传输的性能比较，使用simulink！！！！！！！！！

clc
clear
echo on
%x表示信噪比
x=0:15;
% y表示信号的误比特率，它的长度与x相同
y=x;
% BFSK调制的频率间隔等于24kHz
FrequencySeparation=24000;
% 信源产生信号的bit率等于10kbit/s
BitRate=10000;
% 仿真时间设置为10秒
SimulatonTime=10;
% BFSK调制信号每个符号的抽样数等于2
SamplesPerSymbol=2;

for i=1:length（x）
%     信道的信噪比依次取x中的元素；
    SNR=x（i）;
%     运行仿真程序，得到的误比特率保存在工作区变量BitErrorRate中
    sim（‘BFSK_AWGN‘）;
%     计算BitErrorRate的均值作为本次仿真的误比特率
    y（i）=mean（BitErrorRate）;
end

% 准备一个空白的空间
% hold off;
figure

% 绘制x和y的关系曲线图，纵坐标采用对数表示
semilogy（xy‘-*‘）;
