| 摘 要： | 基于对恒模算法(CMA)和多模算法(MMA)的研究,在两种算法的基础上提出了一种修正的多模算法。计算机仿真的结果表明,与恒模算法以及多模算法相比,该算法有较小的剩余误差和码间串扰(ISI)以及更稳定的收敛效果;而且该算法克服了信道传输引起的相位模糊(相位偏移)。

| Abstract: | In this paper, a modified multi-modulus algorithm is developed for blind channel equalization, which is based on the constant modulus algorithm. Simulations show that the approach has smaller residual error, a more stable convergence and a fewer intersymbol interference (ISI) than those obtained by using the CMA. And the approach can overcome the phase ambiguity(or phase offset). |
