title = "A New Multi-Stage Receiver for Lattice-Coded Based Multiuser Communication",
abstract = "It was shown that by operating over the integer linear combinations (ILCs) of K users' messages, lattice-code based multiple-access (LCMA) offers increased system load and improved error-rate performance over non-lattice based schemes. This paper advances the existing LCMA system by designing a new multi-stage LCMA receiver. In each stage, the receiver attempts to compute as many ILCs as possible. Then, from these ILCs, generalized matrix inversion (GMI) is introduced to recover a subset of K users' messages. These recovered messages are cancelled from the original received signal, yielding an equivalent system with less users for the next stage. Such operation continues successively until all K users' messages are recovered. System loads of up to 400\% and near capacity performance are demonstrated for various MA models.",
