Colored noise reduction using Bark scale spectral subtraction, statistics, and multiple time frames

Estimation of a Type of Form-Invariant Combined Signals under Autoregressive Operators

“…Mihalis Samonas et al [5] used a self-consistent restoration peak preserving algorithm to eliminate the high level additive colored Gaussian noise. David Kozel et al [6] proposed a spectral subtraction algorithm for reducing colored noise from noise-corrupted speech, however with a limitation of the requirement of a favorable signal to noise ratio as with all spectral subtraction algorithms. Jesper Højvang Jensen et al [7] derived the signal amplitude and noise covariance matrix estimator with colored Gaussian noise and extended the existed singlesinusoid algorithm to multiple sinusoids.…”
