% Define the input data
data = [1 0 1 1 0 1 0 0];

% Define the modulation parameters
M = 2;                % Number of symbols in PSK (2 for binary PSK)
frequencies = [100 200]; % Frequencies for FSK modulation

% Modulate the input data
pskSignal = pskmod(data, M);
fskSignal = fskmod(data, frequencies);
askSignal = askmod(data);

% Add white Gaussian noise to the signals
snr = 10; % Signal-to-noise ratio in dB
noisyPskSignal = awgn(pskSignal, snr);
noisyFskSignal = awgn(fskSignal, snr);
noisyAskSignal = awgn(askSignal, snr);

% Plot the original and noisy signals
