COMMUNICATION DEVICES, METHOD FOR DETECTING AN EDGE IN A RECEIVED SIGNAL AND METHOD FOR RECEIVING DATA

A communication device includes a receiver configured to receive a signal, a sampler configured to sample the signal for each digital value of the predefined sequence of digital values in the signal, a memory configured to store a table giving, for each of a plurality of combinations of one or more preceding first digital values and a following second digital value, a threshold for a signal level to detect the second digital value, an initializer configured to, for a combination in a subset of the plurality of combinations, initialize the table based on a sample of the signal for the second value, and for a combination outside of the subset, select a combination from the subset and initialize the table based on a sample of the signal for the second value of the selected combination.
