Patent number: 10033550Abstract: Systems and methods for detecting potentially active user equipment (UE) in a network are provided. A set of potentially active UEs is detected using an iterative method. In a first iteration UE detection is performed using compressed sensing (CS) based on first pilot sequences to detect a first set of potentially active UEs. Channel estimation is then performed for the first set of potentially active UEs. In subsequent iterations, UE detection is performed using CS to detect another set, typically reduced in size, of potentially active UEs using results of the channel estimation from the previous iteration. Channel estimation is then again performed for the new set of potentially active UEs. After the last iteration, the set of potentially active UEs detected in the last iteration is output as the determined set of potentially active UEs along with channel estimates for the set of potentially active UEs determined in last iteration.Type: GrantFiled: March 21, 2016Date of Patent: July 24, 2018Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Javad Abdoli, Ming Jia

Patent number: 10033553Abstract: A video signal and an audio signal are TMDS transmitted from a source device to a sink device. Through a reserved line and a HPD line provided separately from a TMDS transmission line, an Ethernet™ signal is bidirectionally transmitted, and also, a SPDIF signal is transmitted from the sink device to the source device. The Ethernet™ signal bidirectionally transmitted between Ethernet™ transmitter/receiver circuits is differentially transmitted by an amplifier and is received by the amplifier. The SPDIF signal from a SPDIF transmitter circuit is common-mode transmitted from an adder and is received by the adder to be supplied to the SPDIF receiver circuit.Type: GrantFiled: April 19, 2017Date of Patent: July 24, 2018Assignee: Sony CorporationInventors: Gen Ichimura, Hidekazu Kikuchi, Yasuhisa Nakajima

Patent number: 10033556Abstract: Methods, systems, and apparatuses are described for improving the signal integrity of a differential pair of signals by mitigating a non-balanced channel deficiency. For example, signal integrity may be improved by independently shaping and/or independently controlling the slopes (e.g., the rising edge and/or falling edge) of each signal of a differential pair of signals to counteract the effects caused by non-balanced deficiencies to provide a balanced differential pair of signals (i.e., signals having symmetrical impedances, loads, etc.).Type: GrantFiled: October 3, 2016Date of Patent: July 24, 2018Assignee: Avago Technologies General IP (Singapore) Pte.

Patent number: 10033557Abstract: Digital video signals are transmitted from a transmitter to a receiver via a digital video interface including shielded twisted pair cables that are surrounded by an over-braid shield. The over-braid shield is connected to a chassis ground at a transmitting end and the receiving end. An interface conveys the received signals to receiver processing circuitry. The interface is connected to an isolated ground, isolating the receiver processing circuitry. The twisted pairs are also connected to the isolated ground, such that a return current is forced back through the twisted pair cable shields rather than the over-braid shield. This reduces electromagnetic emissions and confines transients primarily to the over-braid shield.Type: GrantFiled: April 6, 2016Date of Patent: July 24, 2018Assignee: L-3 COMMUNICATIONS CORPORATIONInventors: Michael G. Abernathy, Nathaniel Flournoy Lovelace, III
