There is a MATLAB Answers post that discusses the Shannon-Hartley Theorem, which illustrates the theoretical relationship between throughput and SNR for an AWGN channel.
You can refer to the following MATLAB Answers post:
Here is a simple MATLAB code snippet that demonstrates this relationship:
% Parameters
bandwidth = 1e6; % Bandwidth (Hz) - e.g., 1 MHz
SNR_dB = 0:0.5:30; % SNR values in dB
SNR_linear = 10.^(SNR_dB / 10); % Convert dB to linear scale
% Shannon capacity formula: C = B * log2(1 + SNR)
throughput_bps = bandwidth * log2(1 + SNR_linear); % in bits per second
% Plotting
figure;
plot(SNR_dB, throughput_bps / 1e6, 'r-', 'LineWidth', 2);
grid on;
xlabel('SNR (dB)');
ylabel('Throughput (Mbps)');

I hope this answers the question.
