gama.m

it is a simulation about ML synchronization algorithm in OFDM systems,you can slao see a function pi

function gama(d(n,j))
for k=d(n,j):d(n,j)+L-1
gamma(d(n,j))= gamma(d(n,j))+obs_rx(k)*conj(obs_rx(k+N));
pii(d(n,j))=pii(d(n,j))+0.5*( abs(obs_rx(k))^2 + abs(obs_rx(k+N))^2 );
end
lamda(i,d(n,j))=abs(gamma(d(n,j)))- ro*pii(d(n,j));
