Reconstruction of Linear Scrambler with Block Data

Abstract:

In this paper, we proposed a scheme to reconstruct the synchronous scrambler placed after a direct sequence spreader. The scheme was first based on the assumption that the spreading code was known and then extended to the unknown situation. The reconstruction algorithm took advantage of the properties of spreading code that was used to spread the input information sequence. We got a property that helped to detect the multiples of the feedback polynomial. The simulation results proved the validity of the proposed algorithm.
