摘要： The invention relates to a method for channel estimation using a dedicated pilot signal in an OFDM-based communication system with multi-antenna transmission techniques. The receiver estimates the statistical characteristics of a virtual channel generated by beamforming by exploiting the statistical characteristics of common pilot channel, determines the optimum dedicated pilot pattern, and estimates the channel from dedicated pilot signal transmitted in an optimum pattern by means of AMMSE interpolation. The invention minimizes the channel estimation error by exploiting the statistical characteristics of the virtual channel, and optimally determines the dedicated pilot pattern according to the operation environment to maximize the transmission performance in terms of the pilot signaling overhead and the channel estimation error. In particular, the invention is very effective in low signal-to-interference plus noise power ratio (SINR) operation environments.

摘要： An apparatus and method for uplink (UL) power control in a broadband wireless access (BWA) communication system are provided. In a communication method for a base station (BS), the channel gain, noise power and speed of each MS are determined, and the maximum allowable power of each mobile station (MS) are calculated using the determined channel gain, noise power and speed of each MS. Because the UL power is controlled according to the speed of the MS and the distance from the BS, the method can provide higher system capacity than the conventional power adaptation scheme.

摘要： A method for processing a handoff in a mobile communication terminal. If a handoff direction message received from a base station is a hard handoff direction message, the mobile communication terminal transmits an acknowledgement message to the base station in response to the handoff direction message and then performs a hard handoff. If the handoff direction message received from the base station is a soft handoff direction message, the mobile communication terminal performs a soft handoff, incorporates an acknowledgement message into a soft handoff completion message when the soft handoff is completed, and transmits the soft handoff completion message containing the acknowledgement message to the base station.

Further, a method of canceling crosstalk signals in a transmitter includes a step of multiplying the data vectors to be transmitted from a pre-distortion matrix so as to calculate transmission signals, a step of multi-dimensionally decomposing the transmission signals into a time domain and a user domain, a step of precoding the transmission signals in the time domain and precoding the transmission signals in the user domain, a step of multiplying the signals precoded in the time domain and the user domain by the pre-distortion matrix so as to calculate second transmission signals, and a step of multiplying the second transmission signals by the unit matrix and transmitting the result to the receiver.
