Discrete signal synchronization based on a known bit pattern

摘要

Systems and methods for discrete signal synchronization based on a known bit pattern are described. In one aspect of the present subject matter, a discrete signal synchronization system is configured to synchronize a preprocessed discrete signal with a modified discrete signal. The system comprises a processor and a synchronization module coupled to the processor. The synchronization module comprises an extraction module and comparison module. The extraction module determines a bit pattern from the modified discrete signal using Discrete Wavelet Transformation (DWT) and Singular Value Decomposition (SVD). The comparison module compares the determined bit pattern with a known bit pattern of the preprocessed discrete signal and records a time point at which the determined bit pattern matches with the known bit pattern of the preprocessed discrete signal as a synchronization point.

a processor; and a synchronization module coupled to the processor, wherein the synchronization module comprises:
an extraction module configured to determine a bit pattern based on a plurality of singular values, wherein the plurality of singular values are obtained from Discrete Wavelet Transformation (DWT) and Singular Value Decomposition (SVD) of the modified discrete signal; anda comparison module configured to compare the bit pattern with a known bit pattern of the preprocessed discrete signal and to record a time point at which the bit pattern matches with the known bit pattern as a synchronization point.
