Abstract

In this paper, we study systematic Luby Transform (SLT) codes over broadcast channel with the white Gaussian noise. First, we adopt the incremental encoding and decoding method to transmit information. To reduce the multiple users' interference and improve the throughput performance of the system, we proposed a joint BP algorithm which combines the likelihood ratio update with the BP decoding. In addition, we derive the likelihood ratio iterative updating expression. Simulation results show that the proposed decoding method can provide better throughput performance of SLT codes over broadcast channel.
