  • Patent number: 10812140
    Abstract: Embodiments of the invention provide multiple cyclic prefix lengths for either both the data-payload and frame control header or only the data payload. Frame control header (FCH) and data symbols have an associated cyclic prefix. A table is transmitted in the FCH symbols, which includes a cyclic prefix field to identify the cyclic prefix length used in the data payload. A receiver may know the cyclic prefix length used in the FCH symbols in one embodiment. In other embodiments, the receiver does not know the FCH cyclic prefix length and, therefore, attempts to decode the FCH symbols using different possible cyclic prefix lengths until the FCH symbols are successfully decoded.

  • Patent number: 10700740
    Abstract: A communication system and method includes a receiver for receiving a communication signal coupled through a physical medium in accordance with a protocol. An interface formed in a single substrate receives from the receiver an indication of the signal strength of the received communication signal. The interface also decodes the information contained in the received communication signal. For example, the interface sends the information decoded from the received communication signal to a first application for consuming the decoded information. The interface also sends the indication of the signal strength of the received communication signal to a second application for generating a quality determination of the physical medium in response to the indication of the signal strength of the received communication signal.
