跳频通信matlab仿真程序参考

以下是一个简单的跳频通信 matlab 仿真程序：

% 定义跳频序列
hops = [1 2 3 1 2 3 1 2 3];
% 定义数据信号
data = randi([0 1], 1, 100);
% 将数据信号转换为符号序列
symbols = bi2de(reshape(data, 4, [])', 'left-msb');
% 定义调制方式和符号映射
modulation = 'qpsk';
mapping = modem.qpskmod;
% 调制符号序列
modulated = modulate(mapping, symbols);
% 定义采样率和符号持续时间
Fs = 100;
Ts = 1/Fs;
Tsym = 0.01;
% 生成跳频信号
t = 0:Ts:Tsym*length(modulated)-Ts;
fh = hops(mod(0:length(modulated)-1,length(hops))+1);
f = 2*fh/Tsym;
carrier = cos(2*pi*f.*t);
signal = modulated.*carrier;
% 添加高斯白噪声
noise = 0.1*randn(size(signal));
received = signal + noise;
% 解调接收信号
demodulated = demod(received, f(end), Fs, modulation);
demapped = demodulate(mapping, demodulated);
% 将符号序列转换为数据信号
decoded = de2bi(demapped, 4, 'left-msb');
output = reshape(decoded', 1, []);
% 计算误码率
error_rate = sum(xor(data, output))/length(data)

注：此程序仅用于演示目的，实际情况中可能需要添加更多的功能和错误处理。
