path gains and impulse response

Dear all, can any1 tell me how can i compute path gains from channel impulse response. I am obtaining my channel coefficients from SUI channel model now i want to have path gains [complexNum complexNum complexNum](3 path gains with some delay) from channel coefficients (say 3 sets of 200000 channel coefficients)...this mean i have 3 tap model. Can any1 give me hint?
