Samsung patents receiver that cleans up complex data signals
This patent describes a receiver design that uses two separate correction circuits to clean up multi-level data signals. It works by using previously received data to adjust and fix errors in the current signal before the final bit is determined.
In the filing’s own words
A receiver includes a first decision feedback equalization (DFE) circuit configured to receive a first multi-level data signal, and output a first bit correction signal correcting a level of the first multi-level data signal based on first bit data of a second multi-level data signal received before the first multi-level data signal, a second DFE circuit configured to output a DFE signal based on second bit data of the second multi-level data signal and levels of data signals received before the second multi-level data signal, and a slicer configured to determine first bit data of the first multi-level data signal based on a level of the first bit correction signal, and correct the level of the first bit correction signal with a second bit correction signal based on the DFE signal.
What exactly they claim (claim 1)
1. A receiver comprising: a first decision feedback equalization (DFE) circuit configured to receive a first multi-level data signal, and output a first bit correction signal correcting a level of the first multi-level data signal based on first bit data of a second multi-level data signal received before the first multi-level data signal; a second DFE circuit configured to output a DFE signal based on second bit data of the second multi-level data signal and levels of data signals received before the second multi-level data signal; and a slicer configured to determine first bit data of the first multi-level data signal based on a level of the first bit correction signal, correct the level of the first bit correction signal with a second bit correction signal based on the DFE signal, and determine second bit data of the first multi-level data signal based on a level of the second bit correction signal.
