Apparatus and method for detecting synchronization and signals using block data processing

A signal processing method comprising:

• obtaining a cumulative matrix from a vector signal for each frame generated and input from a signal;
• extracting a primary eigenvector from the cumulative matrix;
• calculating a maximum value of a correlation vector from the primary eigenvector;
• detecting a time delay by comparing the maximum value of the correlation vector with a first threshold value;
• calculating a delay correlation vector from the time delay;
• and
• detecting synchronization and signals by comparing the delay correlation vector with a second threshold value.

A signal processing apparatus comprising:

• at least one processor;
• a vector/matrix generator configured to generate a cumulative matrix by converting signal vectors for frames into cumulative vectors, and map the converted cumulative vectors into the cumulative matrix;
• a primary eigenvector extractor configured to extract a primary eigenvector from among eigenvectors corresponding to the cumulative matrix output from the vector/matrix generator;
• a correlation vector calculator configured to:
• calculate correlation values between a preset reference matrix including characteristic information of a transmitted signal and the primary eigenvector, and
• output vectors of the calculated correlation values;
• and
• a signal detector configured to detect current signals by comparing the vectors of the calculated correlation values and a preset threshold value.
