摘要
本文考虑了在白的复高斯乘性和白的复高斯加性噪声中观测的多个复谐波的恢复问题,导出了频率估计以及乘性噪声的样本均值的可计算的Cramer-Rao界(CRB)表达式,模拟结果验证了所得结果的正确性。
The concern here is retrieval of multiple tone harmonics observed in white complex Gaussian multiplicative and additive noises. Computable Cramer Rao bound (CRB) expressions are derived on the frequency estimates as well as on the sample mean of the multiplicative noise processes. Numerical studies support the obtained results.
