摘要： The present invention relates to a method of detecting a space-time code in a mobile communication system. When detecting a space-time code B for a plurality of transmitting antennas, an ML (maximum likelihood) metric, which is generally calculated by using a specific structure of a matrix B, is defined as a new ML metric by reducing a variable of the ML metric. Two dependent sphere decoding processes are performed and an intersection of the decoding results is calculated, and a signal is detected from the ML metric. Therefore, since detection of the space-time code B for the plurality of transmitting antennas is performed by using the newly defined ML metric, an amount of matrix calculated can be reduced, and a calculation amount can be reduced by performing the two dependent sphere decoding processes. Further, since a detection order of symbols is changed according to a channel situation, it is possible to improve the performance of the system.

摘要： Disclosed are a subscriber station authentication method, a protocol configuration method, and a device thereof in a wireless portable Internet system. In the subscriber station authentication method, an authentication mode between a subscriber station (10) and a base station (20) is negotiated, and the authentication mode is negotiated by the base station (20) according to the authentication mode negotiation. The authentication modes include an authentication mode based on the IEEE 802.16 privacy standard protocol and an authentication mode based on the standardized authentication protocol of the upper layer. Authentication is performed by the base station (10) in the case of the authentication mode based on the IEEE 802.16 privacy standard protocol, and the authentication is performed through message transmission using a diameter protocol between a base station (10) and an authentication server (40) in the case of the authentication mode based on the standardized authentication protocol of the upper layer.

摘要： Disclosed is a call admission controlling device and method for providing QoS (quality of service) in the portable Internet. When a mobile terminal requests a guarantee of the corresponding QoS and a call admission, a packet access router calculates a bandwidth available for resource reservation according to mobility characteristics of a cell to which the mobile terminal belongs, and determines resource reserved states according to the mobility characteristics with adjacent cells based on the calculated bandwidth to thus control call admission in order to satisfy a handoff dropping probability of the corresponding cell and prevent disconnected calls when a handoff toward the adjacent cells occurs. As a result, the handoff dropping probability of cells is guaranteed, and the resources are utilized effectively.
