In this paper, we present a hierarchical blind equalization algorithm. It is the combination of CMA(Constant Modulus Algorithm) and DAMA (Multiple Modulus Algorithm). We use CMA at the begining of equalization to make DAMA usable in higher order QAM. After the received signal is equalized to some level, CMA is replaced by DAMA to get a high convergence rate and low residual error.
