帮我找到或者编写一段完整的TSMR代码，要用matlab编译

TSMR (Three-Stage Moving Reflector)是一种用于超高速数据传输的技术，通常在光通信领域应用。在MATLAB中，由于其复杂性和专有库的需求，直接提供完整的TSMR编译代码较为困难。不过，我可以为你展示一个简单的概念示例，这个例子展示了如何创建一个基本的发射器和接收器模型。请注意，实际的TSMR实现需要专业的光学信号处理库如Matlab's Optical Toolbox。

% 定义系统参数
c = physconst('lightspeed'); % 光速
lambda = 1550e-9; % 波长，单位纳米
distance = 1e6; % 距离，单位米
pulse_duration = 1e-12; % 脉冲持续时间，单位秒

% 发射器部分
function signal = transmitter(distance)
    fs = 1/pulse_duration; % 波形采样率
    t = linspace(0, pulse_duration, fs * pulse_duration); % 时间轴
    signal = sin(2*pi*c*lambda*t/distance);
end

% 接收器部分
function received_signal = receiver(signal, distance)
    noise = randn(size(signal)); % 添加噪声
    received_signal = signal + noise;
end

% TSMR通信流程
transmit_distance = distance / 2; % 第一阶段距离
received_first_half = receiver(transmitter(transmit_distance), transmit_distance);

% 中间反射
signal_reflected = received_first_half; % 假设理想反射

% 第二阶段距离
receive_distance_second_half = transmit_distance; % 第二阶段距离
received_second_half = receiver(signal_reflected, receive_distance_second_half);

% 合并两个半程信号
final_received_signal = [received_first_half; received_second_half];
final_received_signal = final_received_signal(end - length(final_received_signal):-1:1); % 去除重复部分

% 显示结果
plot(t, final_received_signal, 'LineWidth', 2);
xlabel('Time (s)');
ylabel('Amplitude');
