Abstract: An embodiment of an arrangement for detecting sequences of digitally modulated symbols from multiple sources. The arrangement identifies a suitable set of candidate values for at least one transmitted sequence of symbols and determines for each candidate value a set of sequences of transmitted symbols. The arrangement estimates at least one further set of sequence of transmitted symbols, calculates a metric for each sequence of transmitted symbols and selects the sequence that maximizes the metric. At the end, a-posteriori bit soft output information for the selected sequence is calculated from the metrics for said sequences. Generally, these calculations are base on the information coming from a channel state information matrix and a-priori information on said modulated symbols from a second module, such as a forward error correction code decoder.

Abstract translation: 用于检测来自多个源的数字调制符号序列的装置的实施例。 该装置为至少一个发送的符号序列识别适当的一组候选值，并且为每个候选值确定发送符号的一组序列。 该装置估计至少一组另外的发送符号序列集合，计算发送符号的每个序列的度量，并选择使度量最大化的序列。 最后，从所述序列的度量计算所选序列的后验位软输出信息。 通常，这些计算基于来自信道状态信息矩阵的信息和来自诸如前向纠错码解码器的第二模块的关于所述调制符号的先验信息。
