N2 - Recently a new approximate expression of the capacity region for a flat-fading Gaussian interference channel has been proposed. This expression handles interference in a optimal manner. Based on this expression, we propose to develop a new power allocation algorithm improving the achievable rate region for non-flat fading Gaussian interference channel using a OFDM modulation. In the ADSL environment undergoing crosstalk, we numerically show that our power allocation scheme provides substantial gain compared to the uniform power allocation as well as the optimal power allocation based on metric treating interference as noise.
