This paper presents an improved local distribution fitting model. Based on the recently proposed local binary fitting (LBF) model and local distribution fitting (LDF) model, this paper modifies the local background and object distribution fitting functions. Thus our model overcomes the limitations of the LDF model with original distribution fitting functions. In addition, this new model incorporates...
The power spectral density estimation of signals plays an important role in the understanding and analysis of the spectral distribution of signals. In this paper, we adopt dyadic wavelet, multi-band wavelet and complex wavelet to estimate the power spectral density of noisy signals, especially to speech signals and complex modulation signals. We also analyze the properties of different wavelet methods...
