Abstract
A symbol detector (110) for generating data symbols from a received signal having multiple signal voltages comprises an analog-to-digital converter (115) for converting the multiple signal voltages to digital values and peak and valley counters (310, 315) coupled to the analog-to-digital converter (115) for tracking the digital values to determine peak and valley values associated with high and low voltages, respectively, of the received signal. The symbol detector (110) further comprises calculation circuitry (120) coupled to the peak and valley counters (310, 315) for calculating upper, lower, and center thresholds in accordance with the peak and valley values and a decoder (125) coupled to the analog-to-digital converter (115) and the calculation circuitry (120) for generating the data symbols in accordance with the digital values and the upper, lower, and center thresholds.
