摘要： This disclosure describes a receiver having equalization with noise de-whitening mitigation for wireless communication. An input port receives, via an antenna, a signal communicated over a wireless communication link, the signal comprising a noise component. Control circuitry performs zero forcing equalization of the received signal to generate a zero forcing equalization result signal. The zero forcing equalization causes de-whitening of the noise component by increasing a correlation among elements of the noise component. The control circuitry mitigates the de-whitening of the noise component by: determining a noise variance value based on channel properties of the wireless communication link, and modifying the zero forcing equalization result signal based on the noise variance value. The modified zero forcing equalization result signal is communicated, via an output port, to log-likelihood ratio (LLR) generation circuitry for LLR computation.

摘要： Embodiments described herein provide a method for creating a low power wake-up radio frame. The method comprises generating, at an access point, a wake-up radio frame for transmission to one or more client stations, determining whether the wake-up radio frame is to be transmitted inside or outside a basic service set associated with the access point, the basic service set having a basic service set identifier that is used to identify the access point. And in response to determining that the wake-up radio frame is to be transmitted outside the basic service set, computing, a target frame check sequence for the wake-up radio frame without using the basic service set identifier associated with the basic service set, appending the target frame check sequence to the wake-up radio frame; and transmitting, to one or more client stations, the wake-up radio frame with the appended target frame check sequence.

摘要： The structures and methods disclosed herein include changing composition of a metal alloy layer in an epitaxial electrode material to achieve tunable work functions for the electrode. In one example, the tunable work function is achieved using a layered structure, in which a crystalline rare earth oxide (REO) layer is epitaxially over a substrate or semiconductor, and a metal layer is over the crystalline REO layer. A semiconductor layer is thus in turn epitaxially grown over the metal layer, with a metal alloy layer over the semiconductor layer such that the ratio of constituents in the metal alloy is used to tune the work function of the metal layer.

摘要： Embodiments described herein provide a method for fragmenting and reassembling data frames on a medium access control (MAC) layer in a wireless local area network. A datagram is received from an application running on a first network device, for transmission over a wireless communication link in the wireless local area network. A negotiation request is initiated with a second network device for determining whether both the first network device and the second network device have enhanced directional multi-gigabit capability (EMDG) for data segmentation and reassembly. When both devices have EMDG capability and the size of the datagram exceeds the maximum size defined by the wireless local area network transmission protocol, the datagram is segmented into a plurality of transmission data units on the MAC layer.

摘要： Embodiments described herein provide a method for an error logging mechanism operated with controller area network (CAN) buses within an Ethernet network. A first interrupt request indicative of a first error condition that occurs at the first CAN bus is received at an Ethernet bridge and from a first CAN controller connected to a first CAN bus. In response to the first interrupt request, the first interrupt request is serviced by retrieving, from a first error register at the first CAN controller, information relating to the first error condition. The information relating to the first error condition is encapsulated in a first frame in compliance with a layer 2 transport protocol for time-sensitive applications. The encapsulated first frame is then sent, via an Ethernet switch, to an error logging device installed at a location remote to the first CAN bus.

摘要： Embodiments described herein provide a method for cross-channel scheduling of high efficiency (HE) multi-user (MU) frame transmission. In some embodiments, channel information and client station information may be obtained for data transmission. An MU frame containing a data field of a first type and two data fields of a second type may be configured to carry scheduling information relating to one or more channels for the data transmission. It may be determined that a current scheduling setting of the two data fields of the second type leads to unbalanced payload between the one or more channels. The two data fields of the second type may then be adjusted for a balanced channel mapping, and the data field of the first type may be adjusted to reflect the balanced channel mapping. Data based on the adjusted data field of the first type and the adjusted two data fields of the second type may be transmitted via the one or more channels.
