Patent ID: 11943083
Assignee: MARVELL ASIA PTE LTD
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A physical layer transceiver for reliably receiving data at a physical layer transceiver of an automobile in the presence of noise or interference, the physical layer transceiver comprising:
matching filters configured to improve a signal-to-noise ratio of a non-equalized signal received at a physical layer transceiver via a communication channel in a high noise or interference automotive environment;
a digital timing loop configured to reduce jitter in the non-equalized signal by tracking a phase of the non-equalized signal using a digital timing loop; and
control circuitry configured to:
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;
search the non-equalized signal for a preamble before initiating a process of receiving payload data, to reduce false data reception caused by noise or interference; and
extract data from the non-equalized signal in the high noise or interference automotive environment, by utilizing a combination of the matching filters, the digital timing loop, the peak tracking algorithm, and the preamble search.
