Abstract
Embodiments of the present disclosure provide a multi-user detection method and apparatus for cell-free Multiple-Input Multiple-Output (MIMO). The method includes: receiving, by a Central Processing Unit (CPU) of a cell-free MIMO system, an MRC merged data symbol stream S=HY of K users transmitted by an Access Point (AP), and multiplying Sby a conjugate transpose matrix Sof Sto obtain a K*K matrix SS; and performing singular value decomposition on the matrix SSto obtain a unitary matrix V and a diagonal matrix A, obtaining a diagonal matrix Λ according to the diagonal matrix A, and estimating sending-end data symbols of the K users by a formula {tilde over (S)}=VΛVS.
