Characterization and Optimization of LDPC Codes for the 2-User Gaussian Multiple Access Channel

Characterization and Optimization of LDPC Codes for the 2-User Gaussian Multiple Access Channel

We address the problem of designing good LDPC codes for the Gaussian multiple access channel (MAC). The framework we choose is to design multiuser LDPC codes with joint belief propagation decoding on the joint graph of the 2-user case. Our main result compared to existing work is to express analytic...
