Patent ID: 6947482

Claim:
A receiver for demodulating an analog signal transmitted by a remote transmitter over a transmission channel, the analog signal including a first ISI component induced by a characteristic of a pulse shaping filter included in the remote transmitter and a second ISI component induced by a characteristic of the transmission channel, the receiver comprising: an analog front end, including an analog-to-digital converter, the analog front end receiving and converting the analog signal to a first digital signal; an equalizer block coupled to the analog front end to receive the first digital signal, the equalizer block compensating the first ISI component in the first digital signal and outputting a second digital signal; and a decision feedback sequence estimation block, including an ISI compensation circuit, the ISI compensation circuit receiving the second digital signal outputted by the equalizer block and compensating the second ISI component in the second digital signal; wherein the equalizer block comprises: an ISI compensation filter having an impulse response substantially inverse of the impulse response of the pulse shaping filter of the remote transmitter, wherein the ISI compensation filter is an inverse partial response filter; and an adaptive gain stage.
