A method and an apparatus are provided for eliminating multi-user interference in a multi-antenna system. In a BS, precoding vector information of at least one interfering user terminal interfering with a user terminal and information about a ratio of the transmission (TX) power of the user terminal to the total TX power of the BS are detected. A control signal including the detected information is transmitted to the user terminal.

Method and apparatus for eliminating multi-user interference in multi-antenna system

Disclosed is a method and an apparatus for self-calibrating direct current (DC) offset and imbalance between orthogonal signals, which may occur in a mobile transceiver. In the apparatus, a transmitter of a mobile terminal functions as a signal generator, and a receiver of the mobile terminal functions as a response characteristic detector. Further, a baseband processor applies test signals to the transmitter, receives the test signals returning from the receiver, and compensates the imbalance and DC offset for the transmitter side and the receiver side by using the test signals.

Method and apparatus for self-calibration in a mobile transceiver

A method is provided for self-calibrating the mismatch and the direct current (DC) offset occurring in a mobile transceiver. The transmitter of the mobile terminal is used as a signal generator and the receiver thereof is used as a response characteristic measurer. The baseband processor calibrates the mismatch and the DC offset for the receiving and transmitting sides using a test signal received from the transmitter. When multiple input subcarriers are used in a mixer present on a reception stage, self-calibration is performed using multiple received test signals obtained from one transmission test signal.

Self-calibration method for use in a mobile transceiver

An apparatus and a method for setting a routing path in System-on-a-Chip (SoC) having an n&#xd7;n net topology-based structure comprising a plurality of intellectual properties (IPs), each with a unique address, and a plurality of switches forming one-to-one correspondence to the IPs, to transmit and receive data between the IPs by using at least one of the switches. Accordingly, an orthogonal code having orthogonality is assigned according to the direction of transmission of each data (that is, output port). Then, an output port where the data is transmitted is determined, and the data is spread based on an orthogonal code assigned to the output ports of the at least one of the switches.

Apparatus and method for setting routing path between routers in chip

A method of establishing a path between routers in a system-on-chip (SoC) of n&#xd7;n mesh topology structure having a plurality of intellectual properties (IPs) each with a unique address and routers corresponding to each of the IPs respectively, including: receiving a routing packet including a hop counter, and updating address information and information of a stored routing table; establishing a path to at least one neighboring router using the updated routing table upon a request to establish the path; and delivering data by using the established path.
