    Abstract: Provided are a state transition method and apparatus, a device, and a storage medium. The method includes: an optical network unit verifies a received physical synchronization sequence field, and transitions the current state according to a verification result. As such, the probability of downstream synchronization detection can be effectively improved, and the probability of missed downstream synchronization detection can be reduced, thereby ensuring the normal operation of a PON system.

    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 SMRC=HHY of K users transmitted by an Access Point (AP), and multiplying SMRC by a conjugate transpose matrix SMRCH of SMRC to obtain a K*K matrix SMRCSMRCH; and performing singular value decomposition on the matrix SMRCSMRCH to 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)}=VΛVHSMRC.

    Abstract: A power divider, a regulation method, a power allocation method, a storage medium, and an electronic device are disclosed. The power divider includes M power division units. The M power division units are cascade connected to form a cascade structure of N levels, each of the power division units includes one input port and two output ports. Each of power division units in a Kth level in the cascade structure satisfies relationships of: input impedance of a power division unit in the Kth level conjugate-matches output impedance of a unit connected to an input port of the power division unit in the Kth level, and output impedance of the power division unit in the Kth level conjugate-matches load impedance of the power division unit in the Kth level, where N, K, and M are positive integers greater than or equal to 1.
