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 performs AUD, CE, and MUD by dealing with the reconstruction of a single block-sparse vector. Although this conventional approach exhibits the superior performance based on block sparsity adaptive subspace pursuit (BSASP), its computational complexity is significantly high. We hence propose boosted approximate message passing (AMP) which converts multiple measurement vector reconstruction into single sparse vector reconstruction by multiplying random vectors and further propose low-complexity GF-NOMA based on our boosted AMP. |
