Abstract: The present application relates to a baseband communications transceiver and a method of operating the baseband communications transceiver. The transceiver comprises an analog front end transmitter section, AFE TX, with a digital to analog converter, DAC, and a transmission, TX, driver; an analog front end receiver section, AFE RX, with an analog-to-digital converter, ADC; at least one equalizer arranged downstream of the AFE RX and implemented on the basis of an adaptive filter; at least one loss encode and a channel monitoring block. The at least one loss encode is configured to determine loss value data indicative of a signal loss on the communication channel based on filter coefficients of the adaptive filter. The channel monitoring block is configured to determine an amplitude control signal, which is provided to control the amplitude of analog signals generated by the TX driver of the AFE TX.

Abstract: Embodiments of a device and method are disclosed. In an embodiment, a method includes receiving, by an electronic control unit of the IVN and from a first communications device of the IVN, a first operations, administration, and management (OAM) notification packet indicating that the first communications device erroneously received a data packet. The first OAM notification packet identifies a first communications protocol type associated with the data packet. The method includes determining that the first communications protocol type matches a second communications protocol type stored in a first incoming stream register table of the electronic control unit, and determining, based on the first communications protocol type matching the second communications protocol type, that a first communication link between the electronic control unit and the first communications device is not an erroneous communication link.

Abstract: Embodiments of a device and method are disclosed. In an embodiment, a physical layer (PHY) device that is compatible with the IEEE 802.3 standard and that utilizes carrier-sense multiple access with collision detection (CSMA/CD) for media access control to a shared media is disclosed. The PHY device includes a physical coding sublayer transmitter (PCS-TX), a physical medium attachment transmitter (PMA-TX), a physical coding sublayer receiver (PCS-RX), a physical medium attachment receiver (PMA-RX), and a media access priority manager configured to initiate transmission of an indication of a priority of a frame that is to be transmitted onto the shared media.

Abstract: The present application relates to an adaptive filter using manageable resource sharing and a method of operating the adaptive filter. The adaptive filter comprises a cluster controller configured for allocating each of several computational blocks to one of several clusters and a routing controller for configuring the routing of tapped delay signals by a routing logic to the respective cluster in accordance with an allocation of the tapped delay signals to the clusters. Each of computational blocks is configured for adjusting one filter coefficient, ci(n), in one cycle of an iterative procedure according to an adaptive convergence algorithm. The number of computational blocks is less than an order of the adaptive filter.

Abstract: The present application relates to an adaptive filter using resource sharing and a method of operating the adaptive filter. The filter comprises at least one computational block, a monitoring block and an offset calculation block. The computational block is configured for adjusting a filter coefficient, ci(n), in an iterative procedure according to an adaptive convergence algorithm. The monitoring block is configured for monitoring the development of the determined filter coefficient, ci(n), during the performing of the iterative procedure. The offset calculation block is configured for determining an offset, Offi, based on a monitored change of the filter coefficient, ci(n), each first time period, T1, and for outputting the determined offset, Offi, to the computational block if the determined filter coefficient, ci(n), has not reached the steady state. The computational block is configured to accept the determined offset, Offi, and to inject the determined offset, Offi, into the iterative procedure.

Abstract: Various embodiments relate to a device for reducing noise in a received signal, the device including a memory; a processor configured to: receive a signal containing narrow band noise which was transmitted over a channel and received at an analog front end; add two separate delays to the signal to generate a first delayed signal and a second delayed signal; apply an adaptive noise cancellation using the first delayed signal and the second delayed signal to estimate the narrow band noise; and remove the narrow band noise based upon the estimated narrow band noise.
