Patent ID: 7447262

Claim:
A receiver applicable in a full-duplex multi-level (Pulse Amplitude Modulation) PAM transceiver for receiving and demodulating an analog signal transmitted at a baud rate by a remote transmitter, comprising: an Analog-to-Digital Converter (ADC) for converting the received analog signal to a digital sample at a fractional baud rate; a digital resampler for converting the fractional baud rate sample with an arbitrary timing phase into a baud rate data sample and a baud rate derivative sample, both at an optimal timing phase; an equalization unit receiving the baud rate data sample so as to adaptively Perform channel equalization at baud rate; and a timing recovery feedback unit for locating the optimal timing phase by receiving the baud rate derivative sample and an output from the equalization unit and outputting an estimate of the timing phase back to the digital resampler.
