    • A detection method of space domain maximum posteriori probability (MAP) in a wireless communication system is a kind of detection technique of space domain MAP in a multi-aerial wireless communication system, which makes the detection of iteration soft interference elimination for the interference signals in the other moments, and makes the MAP detection or the simplified MAP detection for the all signals in current time and space domain. It includes the steps of: taking a fading block as a unit; the received signals are matched and combined in time domain and space domain, and calculating an equivalent channel matrix; making the sequence detection, calculating estimation and variance of the signals before the ending of detecting internal iteration; when the internal iteration detection finishes, the result is outputted, or is outputted after hard decision.
    • 无线通信系统中空间域最大后验概率(MAP)的检测方法是多空中无线通信系统中空间域MAP的一种检测技术,能够对干扰信号的迭代软干扰消除进行检测 在其他时刻,对当前时间和空间域中的所有信号进行MAP检测或简化MAP检测。 它包括以下步骤:以褪色块为单位; 接收信号在时域和空域进行匹配和组合,并计算等效信道矩阵; 在检测内部迭代结束之前进行序列检测,计算信号的估计和方差; 当内部迭代检测结束时,输出结果,或在硬判决后输出。
