But if above positive real condition is satisfied only within some frequency range, the convergence of FXLMS algorithm is dependent on the spreading of power spectral density of the reference signal.
若上述正实条件仅在某些频带上满足，则FXLMS算法的收敛将依赖于参考信号功率谱密度的分布。

A novel synchronization protocol is presented, giving the extension of third party reference broadcast and concerned with the deployed density of WSN nodes.
