any one have sample code of RSMA with uav. if anyone have it please share me

just as title

Answer 1

% Number of BSs

L = 3;

% Number of users per cell

K = 2;

% Number of antennas at each BS

M = 4;

% Total number of users

U = L*K;

% Total number of transmit antennas

N = L*M;

% Total number of UAVs

Q = 2;

% Number of antennas on each UAV

S = 2;

% Total number of UAV antennas

P = S*Q;

% Maximum number of iterations

maxiter = 10;

% Power constraint at each BS (in watts)

Pmax = 1000;

% Total transmit power

Ptot = L*Pmax;

% Channel matrix H

H = randn(N, U) + 1i*randn(N, U);

% Channel matrix G for UAVs

G = randn(P, U) + 1i*randn(P, U);

% Additive white Gaussian noise (AWGN)

noise_power = 0.1;

noise = sqrt(noise_power/2)*(randn(U, 1) + 1i*randn(U, 1));

% Robust Precoding with UAVs (RSMA-UAV)

lambda = 1.0;

delta = 0.1;

% Initialize transmit precoders and equalizers

F = zeros(N, U);

alpha = zeros(P, U);

% Iterate until convergence or maximum number of iterations

for iter = 1:maxiter

% Update precoders and equalizers using MMSE estimator

F = (lambda*H'*H + (1-lambda)*eye(U)) \ (lambda*H'*(G*alpha) + noise);

alpha = (1/delta)*pinv(G*F)*(Ptot - sum(abs(G*F).^2, 1)');

end

% Calculate achievable rates

C = log2(det(eye(U) + (1/noise_power)*(H*F)*(G*alpha)*(G*alpha)'*(F'*H')/...

(eye(U) + (1/noise_power)*(H*F)*(H*F)')));

% Print out the achievable rates

fprintf('Achievable rates:\n');

for u = 1:U

fprintf('User %d: %.4f bps/Hz\n', u, C(u));

end

make sure that this code runs there may be some syntax errrors please have a proper look into this
