الملخص الإنجليزي

The main aim of this thesis is to study and analyze the different types of pseudo-noise (or pseudo-random) sequence generators in digital communication systems using state space method.

State space models have been derived for the first time with new developed algorithms- to describe and analyze linear and nonlinear pseudo-noise generators, Different types of pseudo-noise generators have, been applied in order to investigate the output pseudo-noise sequences, which are used for spread spectrum modulation for direct sequence spread spectrum technique.

The developed technique based on the Z-transform with efficient algorithm has been proposed and successfully employed to find: the linear equivalence of the sequence of pseudo-noise generators.

A newly developed method depending on the 'Trace function'7 has been suggested with' new algorithm to modify the GMW generator by increasing the complexity of the output sequence and good results were' obtained compared with GMW and other generators where the modified generator (M-GMW) -gives them.

Sequence with, complexity higher than other generators.

Moreover, the linear equivalent design of the modified generator (M-GMW) has been done.

An evaluation of the different types of pseudo-noise generators using Z-transform has been developed.

At the end of each developed method or generator, algorithms and Programs were written in MATLAB language.
