摘要： An iterative tree search-based preceding method for a multi-user Multi-Input Multi-Output (MIMO) communication system includes determining a reference value of a cumulative branch metric of a candidate symbol, eliminating candidates having values that exceed the determined reference value of the cumulative branch metric of the candidate symbol, and registering values, which do not exceed the determined reference value of the cumulative branch metric of the candidate symbol, as entries, and selecting the least value from the values registered as the entries. Thereby, the method has low complexity and similar performance compared to an existing Sphere Encoding (SE) technique.

摘要： An apparatus and a method are provided for detecting N number of TX signals in a MIMO wireless communication system. The apparatus includes an RF processor, a channel estimator, and a signal detector. The RF processor converts signals, received through multiple antennas, into baseband signals. The channel estimator estimates channel information of the respective antennas by using the received signals. The signal detector arranges the baseband signals of the respective antennas on the basis of the channel information, calculates a threshold value of each stage, and selects symbols with a cumulative metric smaller than or equal to the threshold value as candidates at each stage, to detect a TX signal vector with N number of symbols.

摘要： A system is provided for performing location update in a wireless mobile communication system that uses an Internet protocol (IP) address and is classified as at least one paging group. A serving base station (BS) sends a message including an identifier of a paging group where the serving BS is located, determines whether there is a change in IP subnet of a mobile station (MS) upon receipt of a location update request from the MS, and upon recognizing a change in IP subnet of the MS, stores information on a new IP subnet and notifies the change in the IP subnet to the MS. Upon detecting a need for location update, the MS sends a request for location update to a serving BS, and receives a location update success notification and an allocated temporary IP address from the serving BS.
