Analytical Framework of LDGM-based Iterative Quantization with Decimation
Qingchuan Wang, Chen He, Lingge Jiang
While iterative quantizers based on low-density generator-matrix (LDGM) codes have been shown to be able to achieve near-ideal distortion performance with comparatively moderate bl…
Design of Nested LDGM-LDPC Codes for Compress-and-Forward in Relay Channel
Zheng Bingbing, Jiang Lingge, He Chen +1
A three terminal relay system with binary erasure channel (BEC) was considered, in which a source forwarded information to a destination with a relay's "assistance". The nested LDG…
Average Entropy Functions
Qi Chen, Chen He, Lingge Jiang +1
The closure of the set of entropy functions associated with n discrete variables, Gammar*n, is a convex cone in (2n-1)- dimensional space, but its full characterization remains an…
Design and Analysis of LDGM-Based Codes for MSE Quantization
Qingchuan Wang, Chen He
Approaching the 1.5329-dB shaping (granular) gain limit in mean-squared error (MSE) quantization of R^n is important in a number of problems, notably dirty-paper coding. For this p…
