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。
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.
