Abstract: Techniques are described that can be used to extend the data transmission rate specified by 10GBASE-KR of IEEE 802.3ap (2007) to more than 10 Gb/s using a multiple lane backplane. A signal for transmission over 10 Gb/s can be divided into multiple streams for transmission over multiple lanes. Multiple transceiver pairs can be used for transmission and receipt of the multiple streams. Each transceiver pair may comply with 10GBASE-KR of IEEE 802.3ap (2007).

Abstract: A wireless local access network (WLAN) radio listens for a beacon for a listening duration on each of multiple channels. Periodically, the WLAN radio changes the channel on which the WLAN radio listens for a beacon. The WLAN radio rotates through all channels until an entire beacon period is listened to. The number of iterations is chosen to minimize the overlap of successive listening durations. The WLAN radio can detect a beacon by detecting an incomplete portion of a beacon.

Abstract: Techniques for signaling capabilities of a mobile station using a capabilities index as well as a fall back mechanism in case of system failure. The capabilities index can represent multiple capabilities of the mobile station. A mobile station can signal to the base station the mobile station's capabilities using a capability index. A base station can interpret the capability index from the mobile station to learn the capabilities of the mobile station. The base station can signal to the mobile station the base station's supported capabilities using a capabilities index. The capabilities utilized between the base station and mobile station are set according to the base station's signaled capabilities.

Abstract: A video scaler is disclosed. A polyphase filter can be used to generate interpolated pixels. The values of pixels adjacent an interpolated pixel are examined to determine variation in values among the adjacent pixels to determine minimum and maximum value variations. The value of the interpolated pixel is limited based on the minimum and maximum value variations. Ringing artifacts can be reduced by limiting the color range of an interpolated pixel.

Abstract: Techniques for use in a blind detection process of information elements. Channels can be allocated into groups. For each group, resource blocks of each channel can be further divided into subspaces. A base station may communicate a number of channels in a group, a number of subspaces allocated to a group of channels, and a bit shift value to all mobile stations via non-specific user channels to a mobile station. The mobile station uses a blind detection scheme and the number of channels allocated per group, a number of sub-spaces per group of channels, and a bit shift value to locate an information element assigned to the mobile station. A number of blind detection trials may be capped to a sum of a number of channels for all allocated groups.

Abstract: Briefly, techniques to provide varying levels of enhanced forward error correction without modifying a line rate of a frame.

Abstract: Techniques are provided for reducing the magnitude of echo tails in a near-end modem. The invention may use an echo tail canceller to generate a signal that cancels echo tail. One characteristic of the echo tail canceller may be determined during a time when only the near-end modem is scheduled to transmit signals. Another characteristic of the echo tail canceller may be determined at approximately the time that a body echo canceller has reached convergence and may be re-determined periodically thereafter. The near-end modem may subtract from any received signal an echo tail canceller signal generated by the echo tail canceller to cancel echo tail from the received signal.

Abstract: Techniques to cancel echo utilizing reduced die space and reduced usage of a time shared processor.

Abstract: A re-timer system that may include a phase recoverer (“PR”), first-in-first-out device (“FIFO”) and retime clock multiplication unit (“CMU”). PR may receive an input signal that suffers from jitter. PR may generate a phase matched signal having substantially the same phase as that of the input signal. To generate the phase matched signal, PR may use a clock signal provided by a single side band oscillator, CMU, or a clock signal having substantially the same level of jitter as that of the input signal to generate the phase matched signal. FIFO may sample the phase matched signal and store such samples. CMU may request and output samples from the FIFO at a frequency determined by a reference clock signal.

Abstract: Briefly, a system that may facilitate system and line loop back diagnostic operations. In one possible implementation, a first transceiver may transmit test signals to a second transceiver. The second transceiver may include a transmitter with the capability to reduce jitter in received test signals prior to transmission of received test signals back to the first transceiver. The first transceiver may determine path integrity characteristics based on the test signals transmitted from the second transceiver.

Abstract: An apparatus and method for detecting a connection to a data transmission network functions by detecting the network signal energy on a network cable while avoiding the problems of excessive power consumption and generation of excessive electrical noise. By monitoring the receive network lines and determining if there is electrical energy on the cable in the form particular to the type of network supported by the network adaptor card, the host computing device can power-down the transceiver associated with the network adaptor card until an active network connection is detected.

Based on test signals transmitted into the medium, the techniques may be used to construct a mosaic waveform with multiple time segments. Each time segment may be based on a gain enhanced received reflected signal and each time segment may have an applied gain that is at a highest level without causing saturation. The techniques may further remove unwanted bridge tap reflection.

Abstract: A technique for de-skewing a group of serial data signals respectively outputted from a group of data lanes includes simultaneously feeding a test signal to inputs of the group of data lanes and monitoring respective outputs thereof. A predetermined data element of the test signal outputted from each of the group of data lanes is respectively detected and respective elapsed times from the detection of the predetermined data element outputted from each of the group of data lanes to the detection that the predetermined data element has been outputted from all of the group of data lanes are measured. The group of serial data signals are then de-skewed by respectively delaying them in accordance with their respective measured elapsed times. The test signal may include the predetermined data element, a lane identifier, and a predetermined number of additional data symbols, the predetermined data element being a predetermined data character.

Abstract: Techniques to determine and indicate the extent to which transitions of an input signal deviate from a desired transition region. In an implementation, an indication may be provided when a transition of an input signal occurs within the desired transition region and an indication may be provided when a transition of an input signal occurs outside the desired transition reagion. In an implementation, a difference between a number of times when input signal transitions occur inside and outside of the desired transition region may be provided. Accordingly, a receiver of the input signal may decide whether to ignore or use the input signal based on the difference between a number of times when input signal transitions occur inside and outside of the desired transition region.
