    Abstract: A computer system including a server computer with a graphical user interface associated with users and a dynamic content database, and a method of assisting users with a multiple stage decision making process. The graphical user interface visualizes objects, mathematical operation and logical operations required for executing a generic decision making process. The method: enables the users to visually express, in a stage by stage form, a particular decision making process; iteratively and responsively provides the users with instructive queries that are arranged to instruct the users how to further define the next stage of the particular process, until the particular decision making process is defined; applies the defined decision making process on the dynamic content database; provides the users with the results of the decision making process; and debugs the decision making process as constructed by the user.

    Abstract: A hybrid type of decision feedback equalizer (DFE) structure that approaches optimal DFE performance is described. The hybrid DFE includes both an intersymbol interference DFE (ISI-DFE) and a noise predictive DFE (NP-DFE). The hybrid DFE structure is designed so that one form of tap values dominates over the other. This allows only the dominate tap values to be used by the transmitter during precoding and reduces the transmitter complexity. In particular, a hybrid DFE is designed so that the I(z) coefficient values dominate over the N(z) coefficient values, where the notation I(z) and N(z), as known in the art, represent the resulting coefficient values after adaptation of the ISI-DFE and the NP-DFE, respectively. A respective Tomlinson precoding scheme in the transmitter uses only the I(z) values. Since only the I(z) values are used in the precoder of the transmitter, the NP-DFE of the receiver is kept active during the communications phase. Conveniently, the continued use of the NP-DFE in the receiver allows the receiver to track small changes in the channel.
