摘要： Disclosed is a method of detecting signals at a receiver of a communication system with a multiple input multiple output antenna. With the signal detection method, a square of the distance between a received signal vector and a channel status-considered transmission symbol vector is calculated first, and the square of the distance is then classified into first and second components. The first component is minimized to calculate a plurality of first soft symbol estimates. A solution set of the first component is calculated on the basis of the plurality of first soft symbol estimates. The second component is minimized to calculate a plurality of second soft symbol estimates. A solution set of the second component is calculated on the basis of the plurality of second soft symbol estimates. A final solution set is calculated by doing the sum of the first component solution set and the second component solution.

摘要： The present invention relates to a transmission symbol detection method in a multiple antenna system. In the present invention, when a channel matrix is estimated through channel estimation, a receiving side calculates a Q matrix and an R matrix through QR decomposition that is more simplified than a typical QR decomposition from an augmented channel matrix that includes the estimated channel matrix. In addition, the receiving side detects symbols having the minimum Euclidean metric by using the two matrixes, as transmission symbols.

摘要： In order to manage a neighbor list of neighboring base stations based on the location of a terminal communicating with a base station of a macrocell with femtocell deployments, the base station divides the macrocell in accordance with a predetermined standard of division, and generates a mobile neighbor advertisement message so as to periodically transmit the generated message to the terminal. At this time, the terminal identifies the current location thereof in the macrocell upon receipt of the pilot signals periodically transmitted from the base station of the macrocell. The terminal obtains information regarding the location of the terminal from the information regarding the femtocells deployed within the respective divided regions and information regarding macrocells neighboring the macrocell through using the mobile neighbor advertisement message to scan base stations.

摘要： This invention is directed to a method for allocating a call in a CDMA base station. Whenever the base station receives a report of the change in the transmission power from channel processors, the level of interference affecting neighboring cells by a cell of its own is measured. In addition, when a new call is attempted, upon comparing the measured level of interference with a predetermined reference level (a threshold value) of interference, it is determined whether a call is allowed (i.e, allocated) or not dependent on a distance between the mobile station and the base station.
