QUANTIZATION FACTOR OF THE DIGITAL FILTER TRANCFERE FUNCTION INFLUENCE OVER ITS CHARACTERISTICS
Tikhobayev V.G., Ryasney J.V., Panarin V.I.
Abstract
There the technique of definition of number of categories of a binary code is considered at quantization of factors of transfer function of the digital filter providing set requirements to accuracy of the amplitude-frequency characteristic. The technique of calculation of an absolute error of the pulse characteristic appearing owing to restriction of number of categories is considered.

EXPEDIENCY ENSEMBLES OF ORTHOGONAL SIGNALS WITH CHANGING DIMENSION IN THE SYSTEM CDMAUSAGE
Zhuk A.R., Chernyak Z.V., Sazonov V.V.
Abstract
The article afters the approach to increasing of efficiency distinguished frequency resources in CDMA system usage, by ensembles of orthogonal signals with changing demension in the process of providing given noise immunity in necessary condition to change the velocity of data transmission. This approach is based on gradual demension changing of orthogonal ensembles signals being described by own acting symmetric matrix vectors.
