Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 19:
20. A non-transitory computer-readable medium having instructions stored thereon that, when executed by control circuitry, cause the control circuitry to:
receive a non-equalized signal at a physical layer transceiver via a communication channel in a high noise or interference automotive environment;
select, using data select circuitry, a logic zero or a logic one;
prepare the non-equalized signal for extraction of data by processing the non-equalized signal using the physical layer transceiver, the physical layer transceiver being configured to:
improve a signal-to-noise ratio of the non-equalized signal using two or more matching filters;
reduce jitter in the non-equalized signal by tracking a phase of the non-equalized signal using a digital timing loop;
compensate for noise or interference distortion in the non-equalized signal by selecting a decision sample defined by a plurality of peaks, the selecting performed based on tracking peaks in the non-equalized signal; and
before initiating a process to receive payload data, to reduce false data reception caused by noise or interference, search the non-equalized signal for a preamble by detecting the preamble based at least in part on the selected logic zero or the logic one, wherein the physical layer transceiver is prevented from receiving data until the preamble is detected to mitigate false data reception caused by noise or interference; and

extracting data from the prepared non-equalized signal.
