A NEW ITERATIVE SPEECH ENHANCEMENT SCHEME BASED ON KALMAN FILTERING



ABSTRACT

A new iterative speech enhancement scheme that can be seen as an approximation to the Expectation-Maximization (EM) algorithm is proposed. The algorithm employs a Kalman filter that models the excitation source as a spectrally white process with a rapidly time-varying variance, which calls for a high temporal resolution estimation of this variance.

Filtering is desirable in many situations in engineering and embedded systems. For example, radio communication signals are corrupted with noise. A good filtering algorithm can remove the noise from electromagnetic signals while retaining the useful information. Another example is power supply voltages. Uninterruptible power supplies are devices that filter line voltages in order to smooth out undesirable fluctuations that might otherwise shorten the lifespan of elec ....etc

GPS and INS Integration with Kalman Filtering for Direct Georeferencing of Airborne Imagery

1 INTRODUCTION
Georeferencing can be defined as a process of obtaining knowledge about the origin of some event
in space-time. Depending on the sensor type, this origin needs to be defined by a number of
parameters such as time, position (location), attitude (orientation) and possibly also the velocity of
the object of the interest. When this information is attained directly by means of measurements
from sensors on-board the vehicle ....etc

Aim of our Project
• The primary goal is to design a MATLAB based simulator for processing of speech signal with the aid of the Kalman filtering technique .To obtain a reconstructed speech signal, which is similar to the input signal.
• To achieve these results, sample speeches were obtained. These were modeled as an autoregressive (AR) process and represented in the state – space domain by the Kalman filter.

In the TMS (transcranial magnetic simulation) method, a pulsed magnetic field created by a coil positioned next to the scalp is used to locally depolarize neurons in brain cortex. It can be easily combined with electroencephalography(EEG) so that regional brain activity in response to direct cortical stimulation can be visulaized. This makes it an important tool for brain mapping and study. theTMS impulse generates high amplitude and long-lasting artifacts that corrupt the EEG trace which is a great disadvantage in the case of a EEG/TMS coregi ....etc
