Description: 这是一篇很好的有关信道估计的文章，
可以用来快速的了解信道估计的基本内容-In this paper, a method for fast blind estimation
of DS-SS signal is proposed which aims at the
Direct-Sequence Spread- Spectrum (DS-SS) signals
with parameters unknown. Considering the
characteristic that Pseudo-Random noise (PN)
sequence modulates the information symbol, we
make use of the method based on the second-order
cyclic-cumulant to estimate the period of PN
sequence, and then the method of segmented
cross-correlation to estimate the synchronous start
bit between the information symbols and the PN
codes. On base of this, a method of multiple
subsection cross-correlation average is used to
estimate the PN sequence. Computer simulations
show that the method can work well on signals at
low signal noise ratio (SNR).

Description: REMOVAL OF NOISE FROM ECG (ELECTROCARDIOGRAPHY) BY USING MATLAB.
EEG (Electroencephalograph) recording from the scalp has biological artifacts and external artifacts. Biological artifacts, which are generated, can be EMG (Electromyography) signal, EOG (Electrooculograph) signal or ECG (Electrocardiograph) signal. These artifacts appear as noise in the recorded EEG signal individually or in a combined manner. Usually physicians are misled by these noisy signals and the EEG analysis can go wrong. This paper presents noise cancellation i.e. removal of noise signal which can be either EMG, ECG or a combination of these two artifacts from the corrupted EEG signal and also signal enhancement both using recurrent learning technique. For this purpose, we have implemented the RTRL (Real Time Recurrent Learning) algorithm,
