Finite rate of innovation sparse sampling for a binary frequency-coded ultrasonic signal
《Journal of Southeast University(English Edition)》2022年第1期27-35,共9页Song Shoupeng Chen Yiqian Xu Baowen Qiu Yue 
The National Natural Science Foundation of China (No.51375217)。
To achieve sparse sampling on a coded ultrasonic signal,the finite rate of innovation(FRI)sparse sampling technique is proposed on a binary frequency-coded(BFC)ultrasonic signal.A framework of FRI-based sparse samplin...

Non-iterative image feature matching algorithm based on reference point correspondences被引量:1
《Journal of Southeast University(English Edition)》2007年第2期190-195,共6页张维中 张丽艳 王小平 丁志安 周玲 
The National Natural Science Foundation of China(No50475041)
Based on the coded and non-coded targets, the targets are extracted from the images according to their size, shape and intensity etc., and thus an improved method to identify the unique identity(D) of every coded ta...

KeyProjectoftheNationalNaturalScienceFoundationofChina(No.60496311).
A new method of constructing regular low-density parity-check (LDPC) codes was proposed. And the novel class of LDPC codes was applied in a coded orthogonal frequency division multiplexing (OFDM) system. This method e...
