Samsung patents receiver filter that adjusts signal thresholds automatically
This patent describes a receiver circuit that cleans up data signals from a transmitter. It uses a specific filter to calculate error and data thresholds, which help the device distinguish between valid data and noise.
In the filing’s own words
Disclosed is a receiver including a pre-processing block that pre-processes a received signal transmitted from an external transmitter and generates a pre-processing signal, an equalization block that generates an equalization signal based on the pre-processing signal and error threshold values, and a threshold generation block that generates the error threshold values and data threshold values. The threshold generation block generates a delay signal obtained by delaying the equalization signal by a unit time interval, generates a filter signal based on subtracting the delay signal from the equalization signal, and generates the error threshold values and the data threshold values based on the filter signal.
What exactly they claim (claim 1)
1. A receiver comprising: a pre-processing circuit configured to pre-process a received signal from an external transmitter, to generate a pre-processing signal; an equalization circuit configured to perform equalization on the pre-processing signal to generate an equalization signal, based on a plurality of error threshold values; and a threshold generation circuit configured to generate the plurality of error threshold values and a plurality of data threshold values, wherein the threshold generation circuit is configured to: generate a delay signal by delaying the equalization signal by a unit time interval, generate a filter signal by subtracting the delay signal from the equalization signal, and generate the plurality of error threshold values and the plurality of data threshold values based on the filter signal.
