| Abstract(in English) | In this paper, we propose low complexity active user detection (AUD), channel estimation (CE), and multiuser detection (MUD) for the grant-free non-orthogonal multiple access (GF-NOMA). Conventional scheme achieves the low-complexity via boosted approximate message passing (AMP), which converts a multiple measurement vector reconstruction (MMVR) into a single measurement vector reconstruction (SMVR) by multiplying random vectors and solves the reconstruction problems iteratively. This approximation however results in the significant performance loss when the number of iterations is small. We hence propose generalized boosted AMP which converts the original multiple measurement vector reconstruction into smaller one by multiplying random matrices and further propose low-complexity GF-NOMA based on this algorithm. Computer simulations confirm that our proposal outperforms the conventional boosted AMP. |
