Digital image information hiding algorithm research based on LDPC code

Autor: Zhong-xun Wang, Xiang-cai Meng

Publikováno v: EURASIP Journal on Image and Video Processing, Vol 2018, Iss 1, Pp 1-12 (2018)

Abstract LDPC (low-density parity-check code) is a parity check code, and its performance is very close to Shannon limit. It is a sort of good channel code which has good ability of error correction. The coding can be introduced to an information-hid

The basic frequency diverse array (FDA) using linearly increasing frequency increments generates a range-angle dependent beampattern. However, it is coupled in range and angle dimensions and is also periodic in range and time, making its applications
