Multichannel data transmission system in the spline bases
The article deals with multichannel digital data transmission system in which the digital signal is transmitted through the manipulation of the harmonic function which performs subcarrier function with different frequency for different channels. However, so far as the video signal with rectangular shape is characterized by a wide spectrum, the resulting signal also has a wide spectrum, which is not acceptable for most of communication systems with a large number of channels. In order to limit the occupied bandwidth in the filter the Hermitian cubic spline filter’s function is used.
