Abstract |
|
Digital predistortion is one of the most capable ways to compensate non-linear characteristic of a power amplifier. In this paper, a new approach which uses least square (LS) adaptive algorithm with cholesky decomposition is presented. If least square algorithm is combined with Cholesky decomposition for finding the inversion matrix of power amplifier model it not only provides high degree of improvement but also improves stability and decrease computation complexity. |
