    • Provided are an apparatus and method for interference cancellation in a BWA communication system. In a receiving apparatus for the interference cancellation, a preamble correlation measurer measures a preamble correlation coefficient from a preamble of a signal received signal. A data rearranger determines a block size to divide the received signal from the preamble correlation coefficient, divides the signal according to the determined block size, and rearranges the divided signals in a Space-Time coding (STC) mode. An estimate weight calculator cross-correlates the output signals of the data rearranger, rearranges the cross-correlated signals, auto-correlates the rearranged signals, and calculates an estimate weight to perform an interpolation operation. An estimate signal decoding/combining unit detects desired signals from signals estimated by the estimate weight calculator and combines the detected signals.
    • 提供了一种用于在BWA通信系统中进行干扰消除的装置和方法。 在干扰消除的接收装置中,前导码相关测量器从信号接收信号的前导码测量前导码相关系数。 数据重排器确定块大小以从前导相关系数除以接收信号,根据所确定的块大小划分信号,并以空时编码(STC)模式重新排列分割的信号。 估计权重计算器对数据重排器的输出信号进行交叉相关,重新排列交叉相关信号,自动关联重新排列的信号,并计算估计权重以执行插值操作。 估计信号解码/组合单元从由估计权重计算器估计的信号中检测所需信号,并组合检测到的信号。
