1. A data processing system, the data processing system comprising:
a first multi-stream noise predictive filter circuit operable to generate a first interim output corresponding to a first data input based upon a non-matrix based combination of the first data input and a previous instance of a second data input; a second multi-stream noise predictive filter circuit operable to generate a second interim output corresponding to the second data input based upon a non-matrix based combination of the second data input and a previous instance of the first data input; and a combining circuit operable to combine at least the first interim output with the second interim output to yield a combination branch metric.
