DTMB Digital TV Signal Frame Header Demodulation Method and Implementation

Published: 23 September 2021 Publication History

Abstract

Aiming at the problem that the frame header demodulation needs to be completed by using DTMB digital TV signal for positioning, the DTMB signal frame structure is analyzed, and the DTMB signal frame header demodulation method is studied. On this basis, the real digital TV signal is collected outdoors and the frame header is demodulated. The demodulated signal is correlated with the locally generated frame header baseband signal. The result shows that the correlation peak interval complies with the national standard of DTMB signal. The correlation results actually verify the correctness of the demodulation method in this article, and lay the foundation for the subsequent use of the PN sequence correlation peak to obtain the transmission delay for wireless positioning.
