Abstract

In this letter, a spatially-coupled low-density parity- check (SC-LDPC) coded ALOHA system with multiuser detection (MUD)-based multiple packet reception (MPR) is studied. A distributed power control scheme based on multiple power levels is proposed for medium and high rate applications. Numerical results show that the proposed scheme can provide noticeable throughput improvement. This improvement is more significant in the cases of fading channels.
