用最小约束阵实现频率、二维到达角和极化的联合估计,大家可以参考一下了.-binding matrix with the minimum frequency, two-dimensional arrival angle and polarization of the joint estimation, we can make reference to the.

构造一组输入为白噪声加三个频率非常接近的正弦波，其信噪比为10dB，观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率，并比较结果。-constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used t

通信原理中以ASK信号为例,对其进行频率估计.先产生ASK信号,然后通过FFT对其进行频率估计.

OFDM下的信道估计，在频率选择性rayleigh信道下五条多径下测试，并作出信道估计性能曲线
