A concept of global frequency response function (GFRF) has been presented. The MIMO modal parameter identification modal has been established, based on the weighting sum of modal shape squares.
提出了整体频响函数的新概念(GFRF) .以振型平方和的形式对全部频响函数进行加权组合，建立了多输入多输出模态参数的识别模型。
The weighting values are determined as a function of frequency based upon a state of a communication channel and the transmission mode of the signal.
所述权重值基于所述信号的通信信道状态和传输模式确定，所述权重值是频率的函数。
Simulations show that the performance of the frequency estimator based on Weighting Function provides an excellent estimate of frequency offset in wireless systems.
最后通过计算机的仿真验证分析，可以看到在无线系统中这种算法确实具有良好的性能。
