Analysis and Optimization of a General Linking Matrix for JSCC Scheme Based on Double LDPC Codes
A key component of the joint source-channel coding (JSCC) scheme based on double low-density parity-check (D-LDPC) codes is the introduction of a linking matrix between the source LDPC code and channel LDPC code, by which the decoding information ...

Double-Layer Low-Density Parity-Check Codes over Multiple-Input Multiple-Output Channels
We introduce a double-layer code based on the combination of a low-density parity-check (LDPC) code with the multiple-input multiple-output (MIMO) system, where the decoding can be done in both inner-iteration and outer-iteration manners.
