Each line card has at least one active transceiver within the same vectoring group, and each line card also has vector logic capable of cancelling crosstalk induced by an active transceiver that is a member of the vectoring group. Further, the line cards are coupled to one another via a ring connection across which vectoring information is passed from one line card to the next. In the event of a failure of one of the line cards, the failed card is bypassed by the vectoring stream so that the operational line cards can continue crosstalk vectoring operations despite such failure.Type: GrantFiled: March 2, 2012Date of Patent: November 17, 2015Assignee: ADTRAN, Inc.Inventors: Richard Goodson, Arlynn Wayne Wilson, Fred Chu

Patent number: 9130736Abstract: A transceiver system having a phase and frequency locked architecture is described. The transceiver system includes a clock and data recovery type receiver, a frequency divider and a transmitter. The clock and data recovery type receiver receives an external signal from a host unit and extracts the external signal to generate a clock signal and a data signal. The frequency divider is used to divide the frequency of the clock signal for generating a reference clock signal. The transmitter transmits output data content based on the reference clock signal.Type: GrantFiled: October 16, 2013Date of Patent: September 8, 2015Assignee: GENESYS LOGIC, INC.Inventor: Ying-Chen Lin

Patent number: 9106533Abstract: Packets of real-time information are sent with a source rate greater than zero kilobits per second, and a time or path or combined time/path diversity rate initially being zero kilobits per second. This results in a quality of service QoS, optionally measured at the sender or the receiver. When the QoS is on an unacceptable side of a threshold of acceptability, the sender sends diversity packets at an increased rate. Increasing the diversity rate while either reducing or maintaining the overall transmission rate is new. CELP-based multiple-description data partitioning sends the base or important information plus a subset of fixed excitation in one packet and sends the base or important information plus the complementary subset of fixed excitation in another packet. Reconstruction produces acceptable quality when only one of the two packets is received and better quality when both packets are received. Reconstruction provides for single and multiple lost packets.Type: GrantFiled: May 6, 2013Date of Patent: August 11, 2015Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Krishnasamy Anandakumar, Vishu R.

Patent number: 9084089Abstract: Methods and systems that facilitate data delivery to electronic devices are disclosed. One aspect pertains to data delivery to electronic devices that are portable, such as, mobile devices. In one embodiment, one mobile device discovers another mobile device within its vicinity. The mobile devices can then wirelessly transmit data from one mobile device to the other. The mobile devices, or their users, can control, request or influence the particular data content being delivered.Type: GrantFiled: April 7, 2014Date of Patent: July 14, 2015Assignee: Apple Inc.Inventors: Stanley C.

Patent number: 9077432Abstract: A two-way relay, a wireless apparatus and a signal processing method thereof are provided. The two-way relay comprises a transceiver and a processor. The transceiver receives a relay receiving signal including a first terminal transmitting signal transmitted by a first wireless apparatus and a second terminal transmitting signal transmitted by a second wireless apparatus. The processor, which is electrically connected to the transceiver, uses a mapping function to transform the relay receiving signal into a relay signal and enables the transceiver to broadcast the relay signal.Type: GrantFiled: October 11, 2013Date of Patent: July 7, 2015Assignee: Institute For Information IndustryInventors: I-Chou Chung, David W. Lin, Shih-Jung Lu, Chun-Che Chien, Tsung-Yu Tsai

Patent number: 9065495Abstract: A two-way relay transmission apparatus applied to multi-input multi-output communication systems that combines signals received from the terminals and performs a modulo operation to the combined signal to concentrate the signal points towards the center of the constellation. And then, the modulo version of the combined signal is broadcasted. As a result, the peak and average relay transmission powers can be reduced.Type: GrantFiled: May 23, 2014Date of Patent: June 23, 2015Assignee: National Chiao Tung UniversityInventors: David W.

Patent number: 9054770Abstract: A communication circuit includes a receiver circuit that provides differential communication by using a first transmission path and a second transmission path. The first transmission path transmits a first signal. The second transmission path transmits a second signal. The receiver circuit includes a compensation circuit that compensates for the attenuation of a current when common mode noise is superimposed on the first signal and on the second signal. The compensation circuit includes a first compensation circuit. The first compensation circuit detects an electric current attenuation of the first signal when the common mode noise is superimposed thereon, and compensates for the attenuation thereof by adding the detected electric current attenuation to the second signal.Type: GrantFiled: October 1, 2014Date of Patent: June 9, 2015Assignee: Renesas Electronics CorporationInventor: Shigeyuki Okabe

Patent number: 9048797Abstract: A remote radio head unit (RRU) system is disclosed. The present invention is based on the method of adaptive digital predistortion to linearize a power amplifier inside the RRU. The power amplifier characteristics such as variation of linearity and asymmetric distortion of the amplifier output signal are monitored by a wideband feedback path and controlled by the adaptation algorithm in a digital module. Therefore, embodiments of the present invention can compensate for the nonlinearities as well as memory effects of the power amplifier systems and also improve performance, in terms of power added efficiency, adjacent channel leakage ratio and peak-to-average power ratio. The present disclosure enables a power amplifier system to be field reconfigurable and support multi-modulation schemes (modulation agnostic), multi-carriers, multi-frequency bands and multi-channels.Type: GrantFiled: July 18, 2014Date of Patent: June 2, 2015Assignee: DALI SYSTEMS CO.

Patent number: 9042404Abstract: The present application discloses apparatus and methods for increasing channel utilization for a high-speed serial interface of an integrated circuit (IC). A new circuit architecture is disclosed which provides circuitry that may be programmed flexibly to support a multitude of different channel bonding schemes. In accordance with one aspect of the invention, the new architecture decouples the granularity of control-signal channel bonding from the granularity of data-aggregation channel bonding. This advantageously allows optimization of configurations for both types of channel bonding. In another aspect of the invention, the logical boundaries of bonded user channels are decoupled from the physical boundaries of the PCS modules. This decoupling advantageously eliminates a rigid constraint of previous architectures.Type: GrantFiled: June 24, 2013Date of Patent: May 26, 2015Assignee: Altera CorporationInventors: Keith Duwel, Michael Menghui Zheng, Vinson Chan, Kalyan Kankipati
