Abstract
For power efficiency, it can be desirable to use a 1-bit ADC or slicer to receive a wired data transmission. A plurality of N samples per baud period are taken. N can be, for example, 4 or more. At least a portion of the samples are included in a window of samples, the size of which is based at least partly on earlier determined values of prior symbols. For example, a polynomial function or other numerical function can be embedded in a lookup table to map previously determined data bits to an address, and the address can be used to control an input of multiplexers to vary the size of the window. The value for a current symbol is determined based at least partly on one or more values within the window of samples.
