An ab initio method for calculating electron-phonon coupling parameters is presented. The method is an extension of the plane-wave-based linear-response method for the calculation of lattice dynamics. Results for the mass enhancement parameter and the electron-phonon spectral function for Al, Pb and Li are presented. Comparisons are made to available experimental data.
