Four sub-channels are used in the forward equalizer and the coefficients of the equalizer are adjusted by the error of constant modulus algorithm. The advantages of FSE and DFE are integrated. The ideal equalization can be obtained as long as the length of the equalizer equal to or bigger than that of the channel, and the algorithm has the characteristics of faster convergence and smaller mean square error.

该算法前馈滤波器采用4路子信道系统模型，用常数模误差函数对均衡器权系数进行调整，综合了分数间隔均衡器和判决反馈均衡器的优点，均衡器权长只要大于或等于信道长度就能完全均衡信道，该算法收敛速度比波特间隔判决反馈盲均衡算法与T/4分数间隔盲均衡算法(T/4FSE)快、均方误差比BSDFE与T/4FSE小，且计算量不变，有利于信息的实时恢复。

The main architecture of multiple WPANs accessing the HAN is proposed. The medium access control-level coordination solution applied in the access point for the coexistence of different communication protocols within WPAN is discussed. The diagram of the adaptive FRESH filter is described. The anti-interference models of the FRESH filter in the scenario of multiple WPANs accessing the HAN are proposed. The minimum mean square error convergence property of the FRESH filter with the change in data point number is analyzed.
