摘要
介绍了几种恒模算法的改进算法。计算机仿真的结果表明,与恒模算法相比,多模算法和构造函数算法有较小的剩余误差和码间串扰以及更稳定的收敛效果。而构造函数算法,修正恒模算法和修正多模算法則克服了信道传输引起的相位模糊(相位偏移)。
Several improved algorithms for constant modulus are introduced in this paper. Simulations show that multi -modulus algorithm and construction function have smaller residual error, a more stable convergence and less intersymbol interference （ISI） than those obtained by using the CMA. And construction function, modified constant modulus algorithm and modified multi -modulus algorithm can overcome the phase ambiguity （or phase offset）.
