    Abstract: A transmitted signal estimate based on signals received in a layer i within a multiple input, multiple output transmission system and based upon selected constellation points for other, previously processed layers is quantized to a nearest constellation point. A list of candidates headed by the nearest constellation point and with remaining candidates presorted by proximity to the head is selected, for each such quantized estimate based on constellation point selections for previously processed layers. To select K best candidates for the transmitted signal estimates of the current layer i, the proximity of the candidates at the head of each list to the signal estimate for the current layer are compared, and the closest candidate is selected. The list containing the selected candidate is advanced, and proximity of the transmitted signal estimate to all list heads is again evaluated and the closest candidate selected.

    Abstract translation: 基于在多输入多输出传输系统内的层i中接收的信号的发射信号估计并且基于用于其它先前处理的层的所选择的星座点被量化为最接近的星座点。 基于先前处理的层的星座点选择，针对每个这样的量化估计，选择由最接近的星座点开头的候选者列表以及与靠近头部预分配的剩余候选者。 为了选择当前层i的发送信号估计的K个最佳候选者，比较每个列表的头部处的候选者与当前层的信号估计的接近度，并选择最接近的候选。 包含所选候选的列表被提前，并且再次评估所发送的信号估计与所有列表头的接近度，并选择最接近的候选。

    Abstract: Disclosed is a location detecting method of an electronic device including determining whether the electronic device enters a first region including a first location that is a specific path and/or specific region, when the electronic device enters the first region, selecting a signal type capable of being supported by the electronic device among a signal type list of items defined as moving path data corresponding to the first location, distinguishing the first data, in which a parameter feature is present, and second data having a maintenance pattern for a moving path, among the signal type, comparing first data of the moving path data with first data of measurement data measured by the electronic device, and when the first data of the moving path data corresponds to the first data of the measurement data, comparing patterns after pre-processing both second data of the moving path data and second data of the measurement data to determine whether to enter the first location.
