    • Systems and methods for providing multiple-input multiple-output (MIMO) detection, comprising a leaf node predictor for receiving a processed communications stream, computing at least one channel metric corresponding to the communications stream for a given channel realization, and generating at least one parameter corresponding to at least one predicted best leaf node candidate for the given channel realization. A MIMO engine receives the at least one parameter and enumerates at least one list of candidate vectors corresponding to the leaf nodes specified by the generated at least one parameter. Some embodiments simulate a MIMO detector over many channel realizations, track channel metric and parameter values used for each channel realization resulting from such simulating, and store, in a look-up table, best values of the tracked values used for a particular channel metric.
    • 用于提供多输入多输出(MIMO)检测的系统和方法,包括用于接收经处理的通信流的叶节点预测器,为给定的信道实现计算对应于通信流的至少一个信道度量,以及生成至少一个 参数对应于给定信道实现的至少一个预测的最佳叶节点候选。 MIMO引擎接收所述至少一个参数,并且列举与由所生成的至少一个参数指定的叶节点相对应的候选向量的至少一个列表。 一些实施例通过许多信道实现来模拟MIMO检测器,跟踪信道度量和用于每个信道实现的参数值,由这样的模拟和存储在查找表中,用于特定信道度量的跟踪值的最佳值。
