Frame Synchronization in Digital Communication Systems

چکیده
This paper introduces the problem of frame synchronization in digital communication receiver and evaluates the performance of using different sequences for frame synchronization such as Barker, NeumanHofman and PN sequences. In this work we use a correlation rule based method where the receiver, after recovering phase value, the given input values are correlated with a sync pattern (marker) and the frame synchronization is obtained by examining the correlation values. Computer simulation is made by using MATLAB-SIMULINK program and the results show that the correlation rule based method has acceptable performance and implementation simplicity.

Modified Sliding-Mode Control Method for Synchronization a Class of Chaotic Fractional-Order Systems with Application in Encryption
In this study, we propose a secure communication scheme based on the synchronization of two identical fractional-order chaotic systems. The fractional-order derivative is in Caputo sense, and for synchronization, we use a robust sliding-mode control scheme. The designed sliding surface is taken simply due to using special technic for fractional-order systems. Also, unlike most manuscripts, the ...

متن کاملImpulsive Stabilization for Control and Synchronization of Chaotic Systems: Theory and Application to Secure Communication
Impulsive control of a chaotic system is ideal for designing digital control schemes where the control laws are generated by digital devices which are discrete in time. In this paper, several theorems on the stability of impulsive control systems are presented. These theorems are then used to find the conditions under which the chaotic systems can be asymptotically controlled to the origin by u...
