Power allocation algorithm in MC-CDMA
Jianming Zhu, Yeheskel Bar-Ness · 2003
We propose an algorithm to allocate power among subcarriers in an MC-CDMA system. The optimal power allocation coefficients turn out to be the maximum eigenvalue eigenvector of the modified projection matrix orthogonal to the interference signal subspace. We also present a simple on-off control algorithm to decrease feedback information.
