Abstract:
A symbol decoder included in a receiver configured to receive information encoded in accordance with a multi-level symbolic scheme and over a multi-dimensional transmission channel, the symbol decoder comprising:an input, coupled to receive an input signal;a first slicer, coupled to detect the input signal with respect to a first one of two disjoint one-dimensional symbol-subsets; anda second slicer, coupled to detect the input signal with respect to a second one of the two disjoint one-dimensional symbol-subsets;wherein the first slicer outputs a first decision term and a first error term with respect to the first one of the two disjoint one-dimensional symbol-subsets, the second slicer outputting a second decision term and a second error term with respect to the second one of the two disjoint one-dimensional symbol-subsets; andwherein each of the first and second error terms is expressed by a digital representation having substantially fewer bits than the input signal.
