Multi-tap decision feed-forward equalizer with precursor and postcursor taps

A decision feedforward equalizer (DFFE), comprising:

• a plurality of precursor taps configured to sample a received signal by time delay amounts;
• a cursor tap configured to sample the received signal by a time delay amount;
• a plurality of postcursor taps configured to sample the received signal by different time delay amounts;
• a plurality of tentative decision slicers corresponding with outputs of the plurality of precursor taps, the cursor tap and the plurality of postcursor taps and configured to receive delayed signals from the plurality of precursor taps, the cursor tap and the plurality of postcursor taps, and to quantize the delayed signals to generate quantized sampled signals;
• multipliers configured to multiply the quantized sampled signals with tap coefficients to reduce noise;
• and
• a summation element configured to combine the multiplied quantized sample signals to compensate precursor and postcursor inter-symbol interference.

A decision feedforward equalizer (DFFE), comprising:

• taps configured to receive an input signal, and to sample the input signal by time delay amounts to produce time delayed samples;
• tentative decision slicers configured to quantize the time delayed samples;
• and
• a summation element configured to combine the quantized time delayed samples to provide an output signal having a desired bit error rate (BER).
