I am doing some wireless communications simulations using Matlab. There are two famous channel models Rayleigh fading and Nakagami fading. I can easily generate Rayleigh fading h=(randn(1,1)+1i*randn(1,1))/sqrt(2).i want to genrate Nakagami fading. If anyone has experience please share the code with me. Thanks

For nakagami channel you have to write two line instead of one. first you have to define the pdf as
pd = makedist('Nakagami','mu',m,'omega',omega);
Then to generate a random smaples from above pdf write as
h = random(pd,N,Itr);
where (N,Itr) is size of channel.

% The channel coefficient with PDF Nakagami-m distributed random variable
pd1 = makedist('nakagami',m_h,o);
h1 = (random(pd1,N,Nt) + j*random(pd1,N,Nt)).*sqrt(0.5); % Tx-IRS % There is no pathloss
h2 = (random(pd1,Nr,N) + j*random(pd1,Nr,N)).*sqrt(0.5); % IRS-Rx % There is no pathloss
%The SI channel between the transmit and receive antennas of Use
pd2 = makedist('nakagami',m_I,oI);
hI = (random(pd2,Nt,Nr) + j*random(pd2,Nt,Nr)).*sqrt(0.5) ;% Rx-Tx
