摘　　要：针对传统的分块均衡控制设计方法,在面对多网络的嵌入式系统均衡滤波时,控制性能不好。提出基于低功耗多网络分集均衡调制的混合滤波器控制系统设计方法,采用多网络调制方法设计混合滤波器,分集均衡器的嵌入式滤波就可以跟踪不断变化的信道,去掉各条路径的相位偏移,对输入信号以码率进行采样,得到低功耗多网络分集均衡调制频率响应,设计分集均衡线性横向均衡器完成调制滤波,最后进行系统硬件电路设计,实现嵌入式控制改进设计。实验结果表明,采用该方法进行嵌入式多网络通信控制,能有效提高网络通信性能,降低误码率及系统功耗,展示了较好的控制特性。For the bad performance of the traditional partitioning equilibrium design method in the face of balanced filter of the multi network embedded system, a hybrid filter control system design method based on low power network more diversity balanced modulation is proposed. Using hybrid filter with multiple network modulation method, diversity equalizer embedded filter can track changing channel, remove every phase shift of the path, the input signal with sampling rate, low power consumption and more balanced network diversity modulation frequency response. After the diversity equalization modulation filter linear transversal equalizer is complete, the system hardware circuit is designed to improve the embedded control design. The experimental results show that the embedded network communication control method can effectively improve the network communication performance, reduce the bit error rate and power consumption of the system, and show better control characteristic.
