+ *
+ * Examples for where to use this block include:

+ * - Simulation of static MIMO-Channels (in that case, \f$\mathbf{A}\f$ is the channel
+ * matrix)
+ * - Summing up streams with variable coefficients
+ *
+ * This block features a special tag propagation mode: When setting the tag propagation
