引入了一种新的准牛顿多用户恒模算法（QN-MUCMA），用于减轻多用户通信中的码间干扰（ISI）和同道干扰（CCI）。与具有去相关成本的传统恒模算法相比，该算法通过利用权重更新方程中的Hessian信息实现了快速收敛。仿真支持算法改进的收敛特性。
A new quasi-Newton multi-user constant modulus algorithm (QN-MUCMA) for mitigation of intersymbol interference (ISI) and cochannel interference (CCI) in multi-user communications is introduced. Compared with the conventional constant modulus algorithm with decorrelation cost, the proposed algorithm achieves fast convergence by the exploitation of Hessian information within the weight update equation. Simulations support the improved convergence properties of the algorithm.
