    Abstract: A multi-user multi-input multi-output (MIMO) method for transmitting signal with a includes: performing a Tomlinson-Harashima pre-coding (THP) on raw data; decomposing a channel matrix to a product of a block triangular matrix and a unitary matrix, and generating a signal to be transmitted by performing a forward filtering on the THP coded data by using the unitary matrix. A multi-user MIMO apparatus for transmitting signal includes an interference pre-eliminating unit, a modulo unit, a forward filtering unit, and a channel matrix decomposing unit. A multi-user MIMO communication system is further provided.

    Abstract: An apparatus and method are disclosed for synchronizing states. A management module selects a file to synchronize between a base and a detachable device. The detachable device provides a display and a network connection for the base if the base and detachable device are connected. A synchronize module establishes a control connection and a data connection between the base and the detachable device and transmits the file to a memory space over the data connection in response to a command communicated over the control connection.
