Fast threshold determination for packet-multiplexed digital communication

A system that determines a threshold value to distinguish between binary signals, the system comprising:

• a bit wise threshold determination device coupled to receive an input signal and that delays the input signal, averages the input signal and the delayed input signal, and outputs the average to an output node, wherein the average represents the threshold value;
• and
• a storage system coupled to the output node and that selectively stores and selectively provides threshold values to the output node;
• a look-up table that stores threshold values and that retrieves a threshold value in response to control signals;
• and
• a digital-to-analog converter coupled to the look-up table and that converts the threshold value into an analog signal.

A system for converting an analog signal into a binary signal, the system comprising:

• a threshold detection system coupled to receive an input signal, wherein the threshold detection system delays the input signal, averages the input signal and the delayed input signal, and outputs the average to an output node and wherein the average represents a threshold signal;
• a storage device coupled to receive the threshold signal from the threshold detection system and that stores the threshold signal;
• wherein the storage device comprises:
• an analog-to-digital converter coupled to receive the threshold signal and that converts the threshold signal into a digital signal;
• and
• a look-up table coupled to the analog-to-digital converter that stores the digital signal;
• and
• a comparator coupled to receive the threshold signal from the storage device and coupled to receive the input signal, wherein the comparator generates a binary signal based on a comparison between the threshold signal and the input signal.
