There exist numerous research areas in the domain of satellite communication. By offering a summary and an example MATLAB code snippet, we suggest some usual research regions within satellite communication:
- Orbital Mechanics Simulation
Goal: Mainly, satellite orbits should be simulated. It is significant to explore their routes.

% Orbital parameters
a = Re + altitude; % Semi-major axis (m)
T = 2 * pi * sqrt(a^3 / mu); % Orbital period (s)
% Time vector
t = linspace(0, T, 1000);
% Calculate position

- Link Budget Analysis
Goal: Through estimating profits and loss, our team plans to assess the practicability of a satellite communication link.
Summary:
- It is appreciable to evaluate received power, path loss, and antenna gains.
- Mainly, the process of link budget analysis should be carried out.
Example Code:
function linkBudgetAnalysis(Pt_dBm, Gt_dB, Gr_dB, frequency, distance)
% Convert dBm to Watts
Pt_W = 10^((Pt_dBm – 30)/10);
% Calculate free-space path loss
c = 3e8; % Speed of light in m/s
lambda = c / frequency; % Wavelength in meters
Lfs_dB = 20*log10(4*pi*distance/lambda);
% Total Link Budget
Pr_dBm = Pt_dBm + Gt_dB + Gr_dB – Lfs_dB;
% Display results
fprintf(‘Transmitter Power: %.2f dBm\n’, Pt_dBm);
fprintf(‘Transmitter Gain: %.2f dB\n’, Gt_dB);
fprintf(‘Receiver Gain: %.2f dB\n’, Gr_dB);

- Signal Processing: QPSK Modulation and Demodulation
Goal: For satellite communication, we intend to apply QPSK modulation and demodulation.
Summary:
- With the aid of QPSK, our team focuses on modulating a binary signal.
- Typically, noise must be appended to the signal.
- Concentrate on demodulating and evaluating the bit error rate (BER).
Example Code:
function qpskModDemod(data, SNR)
% QPSK Modulation
qpskMod = comm.QPSKModulator(‘BitInput’, true);
modData = qpskMod(data);
% Add AWGN noise
rxSig = awgn(modData, SNR, ‘measured’);
% QPSK Demodulation
qpskDemod = comm.QPSKDemodulator(‘BitOutput’, true);
demodData = qpskDemod(rxSig);
% Calculate Bit Error Rate (BER)
[numErrors, ber] = biterr(data, demodData);
% Display results
fprintf(‘Number of Errors: %d\n’, numErrors);
fprintf(‘Bit Error Rate (BER): %.5f\n’, ber);
end
% Example usage

mu = 0.01; % Step size
lms = dsp.LMSFilter(‘Length’, 32, ‘StepSize’, mu);
% Received signal
receivedSignal = desiredSignal + interference + 0.5*randn(size(desiredSignal));
% Apply LMS adaptive filter
[output, err] = lms(receivedSignal, desiredSignal);
% Display results

Goal: In satellite communication, forecast state of a channel through the utilization of neural networks.
Summary:
- To forecast the current state of a channel, we plan to instruct a neural network.

Example Code:
function channelPrediction()
% Generate synthetic data for training
numSamples = 1000;
X = rand(numSamples, 2); % Features: [SNR, interference level]
y = rand(numSamples, 1); % Target: Channel condition (0-1)
% Train a neural network
net = feedforwardnet(10);
net = train(net, X’, y’);
% Predict channel condition for new data
