Code Tracking of DSSS Signal over AWGN Channel

Abstract

Direct sequence spread spectrum (DSSS) communication systems offer significant performance advantages in view of their low probability of intercept, improved performance in multipath fading environments and their ability to avoid interference by spreading the signal over a wide bandwidth hence distributing the power. For the transmitted sequence to be correctly received and demodulated, the spreading sequence used at the receiver should be similar to that employed in the transmitter. This paper utilizes MATLAB Simulink to demonstrate a method of synchronizing the code clock at the receiver with the code clock at the transmitter. This fine alignment process is knownas code tracking.

“…Sadoudi Said et al [14] in their study, we propose a new generator of hyperchaos-based deployment symbols for direct-sequence spread spectrum (DSSS) systems. Mohanad Abdulhamid et al [15] where they studied and designed DSSS of the signal and design s synchronization by Simple code and barely secure protection. Muthna Jasim Fadhil et al [16] where they used methods to decode and protect information by methods of analysis of neural networks.…”
