Hello Vartika,
To simulate spectrum sharing between two network operators in MATLAB, you can use a simple model where each operator randomly selects a frequency channel, ensuring no interference by avoiding channel overlap.
% Parameters
numChannels = 10; % Available channels
numOperators = 2; % Number of operators
numTimeSlots = 100; % Simulation time slots
% Initialize channel allocation matrix
channelAllocation = zeros(numTimeSlots, numOperators);
% Random seed for reproducibility
rng(0);
% Simulation loop
fo
r t = 1:numTimeSlots
for op = 1:numOperators
% Randomly select a channel
selectedChannel = randi(numChannels);
% Ensure no overlap
while ismember(selectedChannel, channelAllocation(t, :))
selectedChannel = randi(numChannels);
end
% Assign channel
channelAllocation(t, op) = selectedChannel;
end
end
% Display and plot results
disp('Channel allocation:');
disp(channelAllocation);
figure;
hold on;
for op = 1:numOperators
plot(1:numTimeSlots, channelAllocation(:, op), '-o', 'DisplayName', ['Operator ' num2str(op)]);
end
xlabel('Time Slot');
ylabel('Channel');
title('Spectrum Sharing');
legend show;
grid on;
hold off;
This basic model provides a foundation for exploring more complex spectrum sharing strategies, such as cognitive radio or auction-based methods.
Hope this helps!
