摘　　要：本文提出了几种自适应方法来跟踪目标用户的幅度,从而克服了基于恒模的盲自适应多址干扰抑制算法中,由于估计幅值选择不合适而造成算法不收敛的缺点,保证了算法的全局收敛,并提高了干扰抑制能力。计算机仿真结果证明了该方法的有效性与可行性。A few lands of adaptive methods to track the desire user's amplitude are proposed to overcome no convergent drawback of the weigh vector due to choose the dispersion constant inaccurately in the blind adaptive constant modulus(CM) algorithm for multi-access interference(MAI) suppression algorithm. So the algorithm has the global convergence and its performance of multi-access interference suppression attains the best. Computer simulation results show that it is effective and feasible method.
