    摘要: Provided are an apparatus and method for canceling interference in a Broadband Wireless Access (BWA) system. The method includes estimating channel coefficient vectors of a plurality of Mobile Stations (MSs) using the same resource; computing a correlation matrix by subtracting a channel coefficient vector of a corresponding MS from a specific tone input vector within the same resource and by auto-correlating the subtracted vector; canceling interference from the data-tone input vector and the channel matrix by using the correlation matrix; and estimating a transmission symbol for each MS by performing Multiple Input Multiple Output (MIMO) detection by using the interference-cancelled input vector and the interference-cancelled channel matrix.

    摘要: A partial iterative detection and decoding apparatus in a Multiple Input Multiple Output (MIMO) system includes a detector for detecting signals received through at least one receive antenna to generate a first soft decision value, a decoder for decoding the first soft decision value to generate a second soft decision value, and a reliability determiner for determining a signal to be iteratively detected and decoded by using the second soft decision value. Accordingly, the complexity of the receiver is reduced and the number of iterations limited due to the complexity is increased, thereby improving the performance of the receiver.

    摘要: A method and an apparatus maximize the capacity of a wireless communication network by taking into consideration inter-cell interference coordination. A home cell's capacity sensitivity to interference is calculated. At least one neighbor cell's capacity sensitivity to interference is collected. And at least one UE located in the home cell is scheduled based on the home cell's capacity sensitivity and the neighbor cell's capacity sensitivity. Accordingly, it is possible to achieve power and allocation control to maximize the capacity of the overall network including neighbor cells increase the system capacity in a cellular system in which inter-cell interference is large, and adaptively perform a UE scheduling in real time to changing distribution of UEs because information on a change in the capacity of each cell is shared by periods.
