具有先验估计的最大熵谱分析
Maximum Entropy Spectral Analysis with Prior Estimation
【摘要】 提出一种具有先验估计的最大熵谱分析方法。仿真结果表明,在低信噪比场合,当某些先验信息已知时,该方法可得到改善的结果。
【Abstract】 A modified algorithm with prior estimation for maximum entropy spectral analysis is proposed. Simulated results demonstrat that the proposed technique provides improved spectral estimates in poor signal/noise environments when some prior information is given.
