Patent ID: 7817714

Claim:
An integrating receiver in a data transmission system operating with a data period, the integrating receiver comprising: a DFE (decision feedback equalizer); and an integrator performing an integration on an output signal of the DFE during one data period to provide an integrator output signal based on the integrated output signal of the DFE, wherein an ISI (inter-symbol interference) of a waveform equalized by the DFE is removed by using data values delayed by one data period and by two data periods, and wherein the DFE comprises: an adder which receives an input signal input to the integrating receiver and first and second feedback data signals provided at an output of a feedback filter, wherein the adder generates the output signal of the DFE based on a sum of the input signal and the first and second feedback data signals; a decider comparing the integrator output signal with a predetermined reference voltage and producing a compared data signal; and the feedback filter receiving at an input the compared data signal, and producing the first and second feedback data signals by respectively delaying the compared data signal by one data period and by two data periods, and multiplying the delayed compared data signals by first and second equalizer coefficients, respectively.
