摘要:
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.

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.

An adjustable write pulse generator is disclosed. The adjustable write pulse generator includes a band-gap reference current, a programmable ring oscillator, a frequency divider and a single pulse generator. The band-gap reference current circuit generates a well-compensated current over a predetermined range of temperatures needed to program a chalcogenide memory cell. The programmable ring oscillator generates a first set of continuous write “0” and write “1” pulse signals based on the well-compensated current. The frequency divider then divides the first set of continuous write “0” and write “1” pulse signals into a second set of continuous write “0” and write “1” pulse signals. The single pulse generator subsequently converts the second set of continuous write “0” and write “1” pulse signals into a single write “0” pulse signal or a single write “1” pulse signal when programming the chalcogenide memory cell.
