生成一段在AWG中加有色散的matlab代码

以下是一段生成在AWG中加有色散的Matlab代码：

% Define the parameters
f_center = 10e9; % Center frequency
f_span = 2e9; % Frequency span
n_points = 1000; % Number of points
bit_rate = 10e9; % Bit rate
roll_off = 0.1; % Roll-off factor
dispersion = 50; % Dispersion value
disp_length = 20; % Dispersion length

% Generate the frequency vector
f_vec = linspace(f_center-f_span/2, f_center+f_span/2, n_points);

% Generate the time vector
t_vec = linspace(-1/(2*bit_rate), 1/(2*bit_rate), n_points);

% Generate the pulse shape
pulse_shape = rcosdesign(roll_off, 6, bit_rate/f_span, 'sqrt');

% Generate the signal
signal = ifft(ifftshift(pulse_shape.*exp(1i*2*pi*f_vec.*t_vec)));

% Add dispersion
dispersion_phase = exp(-1i*dispersion*(f_vec-f_center).^2*disp_length);
signal = signal.*dispersion_phase;

% Plot the signal
figure;
plot(t_vec*1e9, abs(signal).^2);
xlabel('Time (ns)');
ylabel('Power');
title('Signal with Dispersion');

该代码生成了一个带有有色散的信号，其中包括定义的参数，生成频率向量和时间向量，生成脉冲形状，生成信号以及添加色散。最后，绘制了带有色散的信号的图像。
