Abstract

The paper uses the direct subcarrier correction method to change the structure of the Vietnam DVB-T2 signal, making this signal suitable for passive radar applications. The results of the paper show the appropriate processing order and method to correct the structure of the Vietnamese DVB-T2 signal to remove unwanted subpeaks when performing cross-correlation processing to compress the signal.
