However real channels are generally non-minimum phase systems, baud-spaced equalizers exhibit poor performance under this circumstance. 同时由于实际信道往往为非最小相位系统，此时线性均衡器性能不佳。
In this paper, a stable and convergent adaptive control for minimum or nonminimum bilinear systems is established by using weighted least squares. 本文对一类双线性系统，用加权最小二乘辨识方法建立了自适应控制算法，该算法适用于非最小相位系统，且具有大范围渐近收敛和稳定的性质。
